Class MavlinkParser

Creates a parser with an empty buffer.

How many completed frames are waiting to be taken.

Feeds bytes and queues what completed, for a caller that drains later.

Takes the next queued frame, or null when the parser needs more bytes.

Feeds bytes off a link and returns the frames that completed.

Whatever a serial port or socket delivers can be pushed as it arrives, however it is split. Noise between frames is skipped rather than reported, which is what lets a parser join a stream already in progress.
