Extend DShot ESC Telemetry

[mathiasvr]

It has been suggested to extend ESC telemetry to provide information such as missed zero crossings and demag events.

Currently Bluejay only supports rpm (e-period) telemetry according to the specification of bidirectional dshot.
DShot also allows telemetry on a separate wire which is currently only supported by 32-bit ESC firmware.

It needs to be decided whether Bluejay should add support for dshot (separate wire) telemetry and/or if bidirectional dshot (single wire) telemetry should be extended to somehow support different types of information than RPM.

Fettec S2M protocol may be what we need. If it were to be supported on bl32 or bl_s through bluejay then I would believe we would see it become supported in bf.

There is no need to extend telemetry on a separate wire. DHOT telemetry coding repeats almost 50% coded values, so there exist a lot of codification values (7 ranges of 256 values) to codify them making the pertinent modification in Betaflight.
