Add the BassTone feature (0x8305) as a 0-100 slider — subwoofer level
on the G560, hardware-verified.
Fix the Equalizer setting (0x8310), which never built on devices
reporting signed dB limits: getEQInfo dbMin/dbMax are signed (the G560
reports -20..+6) but were unpacked unsigned, tripping the validator's
min/max assertion. The reported bounds are also exclusive — the G560
NACKs writes at exactly dbMin/dbMax — so present dbMin+1..dbMax-1.
Render with the vertical-slider graphic EQ panel. Note: on the G560
the stored curve round-trips but has no audible effect on USB
playback; whether it shapes the aux input path is still unknown.
Rename HEADSET_OUT (0x8320) to JACK_DETECTION: the feature reports
3.5mm jack presence (getJackStatus statuses/available bitmasks), it
is not an output-mode control.
Fix solaar show sending little-endian feature IDs to ROOT.getFeature,
which silently dropped the flags/version column for every
non-palindromic feature ID and displayed unknown features byte-swapped
(the G560's 0x8305 rendered as "unknown:8305 {0583}").
