TUCKER: Add missing buv and c0v opcodes

This commit adds the 'buv' and 'c0v' opcodes which are used to set speech
volume. Because these only seem to be used once in the English demo and
we right now playback all speech at kMaxSoundVolume anyway we can treat
them as NOOPs.

This fixes a bug in said demo which resulted in Bud being unable to talk
to Del.
