[FL-3057] Allow use of any suitable pin for 1-Wire devices (#2350)

Browse Source 
* Add 1-wire thermometer example app stub
* Working 1-wire thermometer app
* Refactor app to use threads
* Clean up code, add comments
* Add CRC checking
* Increase update period
* Fix error in fbt
* Revert the old update period
* Use settable pin in onewire_host
* Use settable pin for onewire_slave
* Clear EXTI flag after callback, make private methods static in onewire_slave
* Do not hardcode GPIO pin number
* Remove iButton hal from furi_hal_rfid
* Remove most of furi_hal_ibutton
* Add some of furi_hal_ibutton back
* Slightly neater code
* Fix formatting
* Fix PVS-studio warnings
* Update CODEOWNERS
* Add furi_hal_gpio_get_ext_pin_number
* Create README.md
* FuriHal: move furi_hal_gpio_get_ext_pin_number to resources
