[FL-3070] iButton system and app refactoring (#2388) * 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 * Update CODEOWNERS * Add furi_hal_gpio_get_ext_pin_number * Create README.md * Temporary get Metakom and Cyfral keys out of the way * Better enum name * Syncing work, does not compile * Syncing work, now compiles * Working read impl for DS1990 and DS1992 * Add the ability to display extended key data * Get rid of DialogEx * Add save and load API * Better iButtonKey encapsulation * Fix crash * Load key code boilerplate * More load key code boilerplate * Minor code cleanup * Implement loading and saving DS1990 keys * Implement the Info scene * Implement loading & saving for DS1992 * Implement read error scene stub * Implement delete confirmation screen * Better error messages (protocol-dependent) * Minor old code cleanup * Remove iButtonDevice, add command callback to iButtonSlave * Implement draft emulation for DS1990 * Better emulation for DS1990 * Initial emulation implementation for DS1992 * Better common command definitions * Use common submenu callback, add protocol list * Improve ViewData screen * Improve scene_add_type * Add stubs for write functionality * Improve naming consistency * Implement writing a DS1992 onto another one * Improve DS1992 write code * Improve DS1992 write code once more * Prepare write_blank for DS1990, delete ibutton_writer * Implement writing DS1990 onto blanks * Fix reading DS1990 * Partially implement writing DS1992 onto blanks * Implement GUI for writing keys * Implement GUI for emulating keys * Reduce memory usage for pretty_format * Automatically truncate data more than 256 bytes * Initial implementation of DS1996 (not tested) * Fix crash due to missing virtual function * Improve emulation code * Improve DS1992 emulation code * Correct return value for onewire_slave_send * Correct return value for onewire_slave_receive * Implement emulation for DS1992 & DS1996 * Better constant names * Simplify & optimise the emulation code * Remove duplicate code * Add skip rom command emulation * Show loading animation for large keys * Implement manual adding & editing of keys * Use buffered file streams to speed up saving & loading * Reset key name before adding a new one * Sync a buffered file stream before saving * Use the DSGeneric protocol as a fallback option * Implement emulation via RPC * Refactor iButton code in preparation for comparator keys * Refactor iButton code in preparation for comparator keys once more * Make some functions static * Make protocols not rely on one_wire classes * Improve ProtocolDict usage * Improve ProtocolDict usage more * Implement reading Metakom & Cyfral keys * Rename some files * Better file structure * Implement a unified interface for misc protocols * Implement a unified interface for dallas protocols * Concrete types for Dallas protocols * Implement a unified interface for all key types * Improved type naming * Improved private types * Proper types in protocol definitions * Implement emulation for Cyfral & Metakom keys * Implement save&load for Metakom & Cyfral keys * Better type names * Rename files, better names * Allocate iButtonProtocols like a normal class * Reset the key each time the start scene is selected * Improve comments and constants * Add ibutton_protocols to SDK headers * Add ibutton_key to SDK headers * Add ibutton_key to SDK headers * Implement reading via cli * Implement emulation via cli * Implement writing Dallas blanks via cli * Correctly revert the editing if cancelled by the user * Correct committing mishap * Elide the long text on the info screen * Change key name for data in Misc keys * Update iButtonFileFormat.md * Remember the key's folder * Save menu position in ReadKeyMenu and SavedKeyMenu * Correct use of preselected path in file browser Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
