hdspmixer: Fix read/write from/to preset files on MADI-like cards

Browse source 
The old hdspmixer (prior to e24e56795e,
that is pre-1.0.24) has used the hard-coded value "14" for
reading/storing 14 ints from/to preset files, however, it's actually
HDSP_MAX_DEST that should be used.

HDSP_MAX_DEST was bumped from 14 to 32 to allow for MADI cards (32
stereo pairs equal 64 output channels on MADI cards)
