Saleae Logic 2 High Level Analyzer: Crossfire decoder for R/C protocol as used by TBS Crossfire, Tracer or ExpressLRS

1. Install the CRSF analyzer in Logic 2 from the extensions menu. 😉
2. Create a new 'Async Serial' analyzer, set the baud rate to 420000, 8N1, LSB, non-inverted.
3. Create a new 'CRSF' analyzer, configure it and pick the previously created 'Async Serial' analyzer.
4. Done. 🚀

This is still a very early release. Currently the following frames are supported:

• Link statistics (0x14)
• RC channels packed (0x16)

The decoder features a state machine that parses all frames so it can easily be extended to decode future frames.
Some groundwork for additional frames already exists.

• CRC check
• Additional supported frames
