SLIX2 emulation support / practical use for Dymo printers (#2783)
* improve digital_signal for longer packets, also clean up code
* added SLIX2 specific features like signature and unknown keys (for issue #2781), added WRITE_PASSWORD handling
* fix NfcV AFI selection
* when NFCV_CMD_READ_MULTI_BLOCK reads beyond memory end, return the maximum possible block's content
* added SLIX2 reading
* fix NXP SYSTEMINFO response check size
* capture the first received password if none was set before
* clear stored data before reading SLIX details renamed slix2_dump functions to slix2_read
* display card block size values as decimal

added ISO15693 (NfcV) reading, saving, emulating and revealing from privacy mode (unlock) (#2316)
* added support for ISO15693 (NfcV) emulation, added support for reading SLIX tags
* SLIX: fixed crash situation when an invalid password was requested
* ISO15693: show emulate menu when opening file
* rename NfcV emulate scene to match other NfcV names
* optimize allocation size for signals
* ISO15693: further optimizations of allocation and free code
* ISO15693: reduce latency on state machine reset
* respond with block security status when option flag is set
* increased maximum memory size to match standard
  added security status handling/load/save
  added SELECT/QUIET handling
  more fine grained allocation routines and checks
  fix memset sizes
* added "Listen NfcV Reader" to sniff traffic from reader to card
* added correct description to delete menu
* also added DSFID/AFI handling and locking
* increase sniff log size
* scale NfcV frequency a bit, add echo mode, fix signal level at the end
* use symbolic modulated/unmodulated GPIO levels
* honor AFI field, decrease verbosity and removed debug code
* refactor defines for less namespace pollution by using NFCV_ prefixes
* correct an oversight that original cards return an generic error when addressing outside block range
* use inverse modulation, increasing readable range significantly
* rework and better document nfc chip initialization
* nfcv code review fixes
* Disable accidentally left on signal debug gpio output
* Improve NFCV Read/Info GUIs. Authored by @xMasterX, committed by @nvx
* Fix crash that occurs when you exit from NFCV emulation and start it again. Authored by @xMasterX, committed by @nvx
* Remove delay from emulation loop. This improves compatibility when the reader is Android.
* Lib: digital signal debug output pin info
