* 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 --------- Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
