Implementation of the RTP protocol in Elixir. 

Implements:
- [RTP: A Transport Protocol for Real-Time Applications](https://datatracker.ietf.org/doc/html/rfc3550)
- [A General Mechanism for RTP Header Extensions](https://datatracker.ietf.org/doc/html/rfc8285)

Includes out-of-the-box support for these RTP header extensions:
- [A Real-time Transport Protocol (RTP) Header Extension for Client-to-Mixer Audio Level Indication](https://datatracker.ietf.org/doc/html/rfc6464)
- [RTP Header Extension for the RTP Control Protocol (RTCP) Source Description Items](https://datatracker.ietf.org/doc/html/rfc7941)
- [RTP Extensions for Transport-wide Congestion Control](https://datatracker.ietf.org/doc/html/draft-holmer-rmcat-transport-wide-cc-extensions-01)

New RTP header extensions can be added by implementing the `ExRTP.Packet.Extension` behaviour.

See [documentation](https://hexdocs.pm/ex_rtp/ExRTP.Packet.html) for usage examples.
