Rewrite PARAMETERS_FIELDS with the actual field layout for each module.
The previous table treated byte 0 as a "state" byte across the board
and shifted every other field by one position; the offset-0 byte is
just the first real field of each struct (NR sensitivity, NG/Comp/
DeEss/DePop threshold, Limiter boost, HPF frequency). Verified field-
by-field against the captured G522 bring-up samples — every parsed
default now matches the device-reported factory value:
NR : sensitivity=40 release=50ms bias=0 attenuation=-6dB
NG : threshold=-45dB attenuation=-15dB attack=1ms hold=150ms
release=250ms
Comp: threshold=-18dB attack=50ms release=400ms post_gain=3dB
pre_gain=0dB ratio=2
DeEss: threshold=-27dB frequency=8000Hz width_q=32 attack=1ms
release=250ms attenuation=-12dB
DePop: threshold=-12dB frequency=100Hz width_q=16 attack=1ms
release=250ms attenuation=-12dB
HPF : frequency=120Hz
Compressor `byte7_packed` was wrong — pre_gain and ratio occupy
distinct bytes (5 / 6 / 7) rather than being bit-packed into byte 7.
HPF frequency moved from offset 1 to offset 0 (we'd been reading
0x7800 = 30720 Hz instead of 0x0078 = 120 Hz).
Add parse_info() to decode GetInfo (fn 0x40) into per-field
{min, max} dicts. Layout is per-field [min, max] back-to-back using
each field's wire encoding. probe_module logs the bounds at INFO so
the corpus shows device-reported ranges alongside the parsed values.
Most fields drop their `(raw)` placeholder labels for proper unit
labels (dB, ms, Hz). De-esser/De-popper width_q stays opaque because
the device-loaded scale constant isn't pinned down.
