Testsuite for the FSK demodulation.

Writes block 0 with each of the four FSK variants selected and sweeps the bit
rate, reads the configuration back with `lf t55xx detect` and reports, per
configuration, whether what came back is what went in.

    00 xx y0 40
    --       -- max 2 blocks
          -- FSK1 4, FSK2 5, FSK1a 6, FSK2a 7
       -- bit rate, 00 04 08 0C 10 14 18 1C = RF/8 16 32 40 50 64 100 128

Needs a T5577 in the field.
