[FL-84] iButton app, dallas emulate + cyfral read, cyfral emulate (#253)

* maxim crc function
* one wire template device and ds1990 classes
* 3 fields for addr
* cyfral emulator lib
* add cyfral read mode, refract rendering and events
* add ADC1_IN14, add adc interrupt
* cyfral read mode
* rename and move api-hal includes folder
* build onewire libs only if we build app
* start in mode 0
