This new branch is used for allowing both nosteamers and linux users to communicate at the same time.
Nosteamers are stuck with CELT codec as they dont support steam/opus.
Linux users are stuck with steam as they dont support celt without manually fixing the .so file.
This branch discards BroadCastVoiceData for instead creating our own SendNetMsg using SVC_VoiceData
that enables us to take opus packets, decode to raw pcm and encode with celt.
that enables us to take celt packets, decode to raw pcm and encode with opus.
currently does the support for nosteamers to hear steam voice chat still have to be improved, but steam users can hear nosteam users very fine.

/** @defgroup opus_custom Opus Custom
* @{
* Opus Custom is an optional part of the Opus specification and
* reference implementation which uses a distinct API from the regular
* API and supports frame sizes that are not normally supported.\ Use
* of Opus Custom is discouraged for all but very special applications
* for which a frame size different from 2.5, 5, 10, or 20 ms is needed
* (for either complexity or latency reasons) and where interoperability
* is less important.
*
* In addition to the interoperability limitations the use of Opus custom
* disables a substantial chunk of the codec and generally lowers the
* quality available at a given bitrate. Normally when an application needs
* a different frame size from the codec it should buffer to match the
* sizes but this adds a small amount of delay which may be important
* in some very low latency applications. Some transports (especially
* constant rate RF transports) may also work best with frames of
* particular durations.
*
* Libopus only supports custom modes if they are enabled at compile time.
*
* The Opus Custom API is similar to the regular API but the
* @ref opus_encoder_create and @ref opus_decoder_create calls take
* an additional mode parameter which is a structure produced by
* a call to @ref opus_custom_mode_create. Both the encoder and decoder
* must create a mode using the same sample rate (fs) and frame size
* (frame size) so these parameters must either be signaled out of band
* or fixed in a particular implementation.
*
* Similar to regular Opus the custom modes support on the fly frame size
* switching, but the sizes available depend on the particular frame size in
* use. For some initial frame sizes on a single on the fly size is available.

/** @defgroup opus_multistream Opus Multistream API
* @{
*
* The multistream API allows individual Opus streams to be combined into a
* single packet, enabling support for up to 255 channels. Unlike an
* elementary Opus stream, the encoder and decoder must negotiate the channel
* configuration before the decoder can successfully interpret the data in the
* packets produced by the encoder. Some basic information, such as packet
* duration, can be computed without any special negotiation.
*
* The format for multistream Opus packets is defined in
* <a href="https://tools.ietf.org/html/rfc7845">RFC 7845</a>
* and is based on the self-delimited Opus framing described in Appendix B of
* <a href="https://tools.ietf.org/html/rfc6716">RFC 6716</a>.
* Normal Opus packets are just a degenerate case of multistream Opus packets,
* and can be encoded or decoded with the multistream API by setting
* <code>streams</code> to <code>1</code> when initializing the encoder or
* decoder.
*
* Multistream Opus streams can contain up to 255 elementary Opus streams.
* These may be either "uncoupled" or "coupled", indicating that the decoder
* is configured to decode them to either 1 or 2 channels, respectively.
* The streams are ordered so that all coupled streams appear at the
* beginning.
*
* A <code>mapping</code> table defines which decoded channel <code>i</code>
* should be used for each input/output (I/O) channel <code>j</code>. This table is
* typically provided as an unsigned char array.
* Let <code>i = mapping[j]</code> be the index for I/O channel <code>j</code>.
* If <code>i < 2*coupled_streams</code>, then I/O channel <code>j</code> is
* encoded as the left channel of stream <code>(i/2)</code> if <code>i</code>
* is even, or as the right channel of stream <code>(i/2)</code> if
* <code>i</code> is odd. Otherwise, I/O channel <code>j</code> is encoded as
* mono in stream <code>(i - coupled_streams)</code>, unless it has the special
* value 255, in which case it is omitted from the encoding entirely (the
* decoder will reproduce it as silence). Each value <code>i</code> must either
* be the special value 255 or be less than <code>streams + coupled_streams</code>.
*
* The output channels specified by the encoder
* should use the
* <a href="https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-810004.3.9">Vorbis
* channel ordering</a>. A decoder may wish to apply an additional permutation
* to the mapping the encoder used to achieve a different output channel
* order (e.g. for outputting in WAV order).
*
* Each multistream packet contains an Opus packet for each stream, and all of
* the Opus packets in a single multistream packet must have the same
* duration. Therefore the duration of a multistream packet can be extracted
* from the TOC sequence of the first stream, which is located at the
* beginning of the packet, just like an elementary Opus stream:
*
* @code
* int nb_samples;
* int nb_frames;
* nb_frames = opus_packet_get_nb_frames(data, len);
* if (nb_frames < 1)
* return nb_frames;
* nb_samples = opus_packet_get_samples_per_frame(data, 48000) * nb_frames;
* @endcode
*
* The general encoding and decoding process proceeds exactly the same as in
* the normal @ref opus_encoder and @ref opus_decoder APIs.
* See their documentation for an overview of how to use the corresponding
* multistream functions.
