Dont include videoDepacketizer in VP1Packet

[jech]

Now that we have separated the Packet/Depacketizer roles for
the AV1 codec, there is no need to include the videoDepacketizer
mixin in AV1Packet.

@jech thank you it's getting deprecated anyway with the payloader rewrite #295 probably removed by the next major release as it has no use for now, And i didn't want to remove it or changed in cause someone is using it.

[JoeTurki]

I'll make a proper av1 bitstream and frame reader, and a parser for some OBUs like sq header, but this would fit more in webrtc,

[jech]

Let's move h.264 to the same style, so we can remove state from H264Packet and move it into H264Depacketizer. But first, I need to move Galene to Pion v4 (I've been waiting on pion/webrtc#2994 and on pion/webrtc#3003, but I guess they won't happen in time).

[JoeTurki]

@jech I'm going to start with H264 enhancements just after AV1, and planning to fix all the reported bugs, and optimize it more, bring it up to the spec more, and will make a H264Depacketizer too :)

@jech Sean added the TWCC to the v4.1.0 milestone I'll help with this after I finish my todo list for this milestone.
