audioconvert: move dither and noise to fmt-ops

Browse source 
We need to do dithering and noise when converting f32 to the
target format. This is more natural because we can work in 32 bits
integers instead of floats.

This will also make it possible to actually calculate the error between
source and target values and implement some sort of feedback and
noise shaping later.
