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 Co-authored-by: Tiernan Messmer <tiernan.messmer@gmail.com> Co-authored-by: MX <10697207+xMasterX@users.noreply.github.com> Co-authored-by: gornekich <n.gorbadey@gmail.com> Co-authored-by: あく <alleteam@gmail.com>
