API CHANGE: Update ma_clip_samples_f32() to take an input and output.

Browse Source 
The previous version only allowed in-place clipping, whereas the new
one supports clipping into a separate buffer. The input and output
buffers can point to the same buffer in which case the clip will be
performed in-place.
