RTP Packet Decoder/Encoder

The `rtp` library is a Python library for decoding, encoding, and interacting with Real-time Transport Protocol (RTP) packets. Currently at version 0.0.4, it is under active development by BBC R&D. This library is designed to be payload-agnostic and does not provide network functionality or handle specific payload bitstreams; it is intended to be used in conjunction with other libraries for those purposes.
