LED Dimmer (#13776)

* LED Dimmer

Build with EXTRA_FLAGS=-DUSE_LED_STRIP

Tested on SpeedyBeeF7V3

Added adjrange to update the ledstrip_brightness variable. This allows for easy changing of LEDs without having to connect to the configurator.

* Added Unit Tests, Space to Tab

Added unit tests into rx_controls_unittest.cc. The LED brightness is returned as 50 for testing purposes.

Changed tabs in ledstrip.c & .h and rc_adjustments.c to 4 spaces for coding standards.

* Update src/main/fc/rc_adjustments.h

Missed a tab in rc_adjustments.h
