Migrate to WHIP (#1120)

* migrate to whip part1

* migrate to whip part2

* migrate to whip part3

* migrate to whip part4

* migrate to whip/whep with bidirectional

* migrate to whip/whep with bidirectional

* use next library

* add _next to lid datachannel files

* cleanup and add todos

* use internal helper rtcGetPayloadTypesForCodec

* fix lint

* refactor decode()

* move logic to codecs

* move logic to codecs

* break encoders and decoders into multiple files

* break encoders and decoders into multiple files

* cleanup more

* drop action for stream endpoints, keep type for self documentation

* restore the v4 store

* fix: align frame_width and frame_height to even in both collect() and read_resolution() in both decoders.
