move voicemeetertype(), voicemeeterversion() and samplerate() properties into VbanPacket

add NamedTuples for Levels, Labels and States.

refactor the levels properties

update the math in util.comp()

StripLevel/BusLevel getters updated according to changes in VbanPacketNBS0

remove {VbanCmd}._get_levels(), it's no longer necessary.
