New lf rfid (#342)
* invert inputs
* move RFID RX to IRQ, unstable
* remove critical blink
* supress short carrier, decrease queue
* migrate to stream buffer
* enable state change
* conditions build for invert RFID IN
* move get_rfid_in_level
* use hal function for get comp level, remove duplicate interrupt registration, interrupt unregister on exit
* reinit comparator context on mode change
