* Update multi protocols
* SFHSS also has failsafe implemented
* Show failsafe setting in Companion
* Fix missing protocol names
* Update failsafe format and only show bind when module reports to support it
* implementing syncing with multi
* Send config command
* Implement setting failsafe for multimodule
* Fix
* Fix last bugs. Multi sync now working as expected.
* Add eww multi protocol
* Add FY805 protocol
* Fix stray space
* Fix multi sending 120% instead of 100%.
* Implement a custom telemetry for the multi module
The custom telemetry allows the module to tell the telemetry protocol to OpenTX and also allows signaling the status of the Module (e.g. invalid protocol) to OpenTX
This should also close#3979.
* Cosmetics and a few small bugfixes
* remove empty if
* Move status line directly below the mode to be always visible when selecting a protocol
* warn if internal RF module is on
* Replace sprint with small helper function to build on AVR ARM (AR9X, 9XPRO, …)
* TR in wrong order, RF_PROTO_OFF inverted
* Refactor definition of Multimodule protocols to have one central place to define all multi protocol properties
* Also update protocols in companion
* Update multi version number to display as a.b.c.d
