Fix MiFare DESFire GetKeySettings response parsing (#1267)
Only the bottom nybble of buf[1] is the key ID; the top nybble contains flags.
Notably, the top bit is set for AES mode on EV1+ cards, and ORCA cards in the
Seattle area were just upgraded to include an app that uses AES.

Prior to this, cards with flags set could be read and saved just fine, but
loading them would fail due to missing keys.  After this, tags saved with the
old version will load fine, and when re-saved will have the flags separated
out into a new field.

Nfc: add basic Mifare DESFire support (#1024)
* Fix TextBox word wrap behavior
* Wrap width is 120 pixels, not 140. (140 is larger than the screen!)
* Glyph width already includes spacing; don't add 1 additional px
* When starting a new line, include wrapped glyph width in new line_width.
* Call canvas_set_font before text_box_insert_endline so that glyph
  width is calculated using correct font.
  Previous approach worked somewhat well using default TextBoxFontText but
  this version is more robust, particularly when using TextBoxFontHex.
* Add basic Mifare DESFire reading, file/app browser
* Fix build with APP_ARCHIVE=0
* Add bool type to flipper_format
* Add ability to save and load DESFire card data
* Skip over NfcSceneDeviceInfo when viewing saved DESFire info
* mf_df_clear: don't leak master key settings key versions
* When opening a DESFire card from Archive, retain UID emulation behavior
* rm unnecessary \r\n
* show Popup instead of leaving view in bad state
* Move NfcReaderRequestData out of union
  This makes it safe to emulate DESFire/EMV without clobbering card data.
* Display saved DESFire cards via NfcSceneDeviceInfo
* Display and save file metadata even when contents are missing
  This can happen when a file doesn't allow unauthenticated reads (see the
  call to mf_df_parse_read_data_response in nfc_worker.c).
