[opus] 24 bits samples

Well, if you're on a fixed-point DSP, then you shouldn't use the float
API. In that case, your only option is to downshift to 16-bit and use
the int API.

OPUS_SET_LSB_DEPTH is just for telling the encoder where the noise floor
is. In this case you don't need it at all. I especially hope you weren't
passing "16/24" since that would equal zero and tell the encoder that
all your input is noise and it can consider it as silence.
