pw_cobs: Consistent Overhead Byte Stuffing (COBS) codec and zero-copy frame streamer

pw_cobs is designed for small Flash and RAM footprints on microcontrollers.

The table below shows the incremental Flash footprint of:

• One-shot COBS encode and decode (Encode and Decode).

• In-place EncodeBuffer (EncodeBuffer and EncodeInPlace).

• Streaming COBS Decoder (Decoder).

• All COBS primitives combined.
