* 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
