protocols.decode_awid: FSK2a (no Manchester) via the ported detectAWID path, then
removeParity — the 88 bits after the preamble are 22 groups of 3 data + 1 odd-parity
bit, so stripping parity gives 66 bits whose first byte is the format length
(26/34/36/37/50) and the rest the facility/card fields (cmdlfawid.c index map). The 22
parity checks stand in for AWID's missing CRC, so it can't false-positive. Added to the
identify decoder chain.
Tests: AWID-26 round-trip across fc/card, parity gate rejects noise/EM4100. Full suite green.
LF stack now covers EM4100, HID, AWID, FDX-B + T55xx config. Indala (PSK) queued — the
one path needing real PSK phase-tracking (DetectPSKClock/pskRawDemod), best tuned against
a hardware capture.
