fix(icom): the IC-7760's attenuator is the stepped 6/12/18 dB kind

Browse Source 
Confirmed on a real one. It was falling into the single-20 dB default, whose
one button the rig NAKs.

// Attenuator steps are MODEL-dependent even though the CI-V command (0x11) is the

// e.g. 6 dB on a 7300). Default to the common single 20 dB for unknown models.
