[FL-2393][FL-2381] iButton, OneWire: move to plain C (#1068)

* iButton: getting started on the worker concept
* Hal delay: added global instructions_per_us variable
* iButton: one wire slave
* iButton: ibutton key setter
* iButton: one wire host, use ibutton_hal
* iButton\RFID: common pulse decoder concept
* iButton: cyfral decoder
* iButton: worker thread concept
* iButton: metakom decoder
* iButton: write key through worker
* iButton: worker mode holder
* iButton: worker improvements
* iButton: Cyfral encoder
* iButton: Metakom encoder
* lib: pulse protocol helpers
* iButton: Metakom decoder
* iButton: Cyfral decoder
* iButton worker: separate modes
* iButton: libs documentation
* HAL: iButton gpio modes
* iButton worker: rename modes file
* iButton worker, hal: move to LL
* iButton CLI: worker for reading and emulation commands
* iButton HAL: correct init and emulation sequence
* iButton cli: moved to plain C
* iButton: move to worker, small step to plain C
* Libs, one wire: move to plain C
* Libs: added forgotten files to compilation
* iButton writer: get rid of manual disable/enable irq
