EmuFlight 0.4.2 / BMI270, ICM42688P targets and Helio/Strix fixes

EmuFlight 0.4.2 - Helio fixes and BMI270 / ICM42688P support.

• does not contain all targets, as no significant flight changes.

Caution

DJI components bypass Configurator/USB safety-checks. Do not attempt arming while connected to Configurator with battery plugged. Always remove propellers and use a smoke-stopper for extra safety.

Warning

3D mode is broken.

Changes:

• This release is still Analog-only (no MSP-Display-port).
• [bugfix] fixes STABLE-MODE for HELIOSPRING, STRIXF10, and MODE2FLUX (#886).
• [bugfix] Fix the correction yaw gives in 2pass (#852).
• [feature] CLI option to apply dynamic-notches to RP vs normal/default RPY (#881). (set dynamic_gyro_notch_axis = [RP|RPY])
• [feature] adds ICM42688P support (#891).
• [bugfix] ICM426XX - Disable AFSR (#933).
• [feature] adds BMI270 support (#930).
  • Note: Configurator wrongly shows 8k loop rates. CLI will show proper 3.2k.
• [enhancement] add Gyro LPF2 type to OSD (#934).
• minor fixes/additions not affecting flight.
• [targets] adds some, not all, BMI270 and ICM42688P based targets.
  • Note: New target requests accepted in Emuflight Discord or GitHub Issue tracker.
