- A write needs both a location and data. NTAG WRITE (0xA2) already did;
the two-phase 0xA0 writes (Type 2 COMPAT_WRITE, MIFARE Classic WRITE)
only took the page/block. They now take (page/block, data) and build a
frame *list* — the command frame plus the 16-byte data frame.
- Catalog build() may now return a list of frames; _handle_call sends each
in sequence and traces every exchange (so both phases of a write show).
- 14a catalog commands now append the ISO14443-A CRC (ISO14A_APPEND_CRC),
which real tags require — manual raw hex is still sent verbatim.
3 new/updated tests (two-phase build + send, CRC flag on reads).
