* Update api_symbols.csv * Ultralight C 3des implementation added * Access check for Ultralight cards is now splitted into 2 functions one for ULC card and another for common * Ultralight C authentication command handlers added * Update api_symbols.csv and api_symbols.csv * Length added to ultralight encrypt function * New structure for storing 3des key added * Reseting of 3des_key added * des_context init/deinit added to poller * New poller step for ultralight c auth added * Added ultralight c des key to application * Renamed felica unlock scenes to more generic des auth scenes, because they are now used also for ultralight c * Show different menus for different ultralight card types * Update api_symbols.csv and api_symbols.csv * Some macro defines added * Different amount of pages will be now read for ultralight C and others * New unit test for ultralight C * Some comments and macro replacements * New function added to api * Now all data read checks mfulC separately * Adjusted listener to handle missing 3des_key properly * Now poller populates 3des_key after reading with auth to card data * Nfc: rename _3des_key to tdes_key * Bump API Symbols * Mute PVS Warnings Co-authored-by: hedger <hedger@users.noreply.github.com> Co-authored-by: gornekich <n.gorbadey@gmail.com> Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
