[FL-1449] Indala reading and writing (#616)
* Rfid: indala 40134 validation and decoding
* Rfid: show indala info
* Rfid: decoder to output comparator signal on gpio pins
* Rfid: working indala 40134 decoder
* HAL: added function to change rfid timer parameters on the fly
* RFID: Indala reading, card detection, card verification
* Rfid: indala writing
