Add complete Indala 224-bit protocol: decode, encode, emulate, and write/clone via T5577. Uses PSK2 modulation (RF/32, bitrate 2) with a 30-bit preamble (1 + 29 zeros) and 224-bit data payload. Decoder performs PSK2 differential decoding (data = phase XOR next_phase) from the shift register, handles both normal and inverted preambles for phase-alternating cards, and validates across 6 consecutive frames. Writer configures T5577 with block 0 = 0x000820E0 matching Proxmark3 reference implementation. Encoder uses PSK2 carrier-flip modulation where carrier phase inverts on data bit = 1. Verified against Proxmark3 lf indala clone output: 80000001B23523A6C2E31EBA3CBEE4AFB3C6AD1FCF649393928C14E5 Includes unit tests for roundtrip encode/decode and PSK2 phase alternation edge case.
