* Made nfc_device_save accept full path as an argument
* Move from cstrs to furi strings and fix logic
* nfc tests: fix memory leak
* nfc: add mf_classic_get_total_blocks() to API
* nfc tests: simplify nfc tests
* nfc: fix memory leak in shadow file saving
* nfc: fix set uid scene
* nfc: fix saving files
