[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
