Other fixes and improvements

Compatibility

This is a bugfix/patch release and is compatible with earlier 3.x versions.

Who should update from V3.6.2?

These are all backports from bugs found during 4.0.0-RC1 testing and seek to improve stability and performance for users experiencing:

Rotorflight Configurator over wifi frequently disconnects before the tab can load
Poor wifi / bluetooth connection stability caused by backpack being active when in these modes
Telemetry stops updating when used with external telemetry sensors that generate malformed packets connected to the receiver
SPI receivers constant connect/disconnect cycles due to VTX Admin on connect
Note! elrs.lua from V4.0.0-RC2 (r16) can be used with 3.x as well. The version number has been removed and is compatible with ExpressLRS 2.x, 3.x, and 4.x
