[FL-85][FL-446][FL-720] Dallas key blanks and OneWire lib rework (#313)
* sepate one wire class
* TM2004 writer
* app mode write ds1990
* test another blanks protocol
* new ibutton slave
* one wire states
* tim1 capture compare and update interrupts
* interrupt mgr, new timers IRQ
* discard HAL_TIM_PeriodElapsedCallback from main
* add exti_14 line
* add external interrupt callback
* use int mgr in input
* better interrupt managment
* add interrupt callback enable and disable fns
* properly init app
* changed timings
* rename one wire classes
* use new owb classes
* properly remove interrupts
* new blanks writer
* remove unused tests
* new core includes
* extern c guard
* fix api_interrupt_remove usage
* remove debug info, new way to detect blanks writing
* remove copy constructor
* change keys template
* fix app sources recipe
