Rework the converter to use the pack/unpack functions Because the unpack functions can only unpack to 1 format, add a separate conversion step for doubles when the unpack function produces int. Do conversion to S32 in the quantize function directly. Tweak the conversion factor for doing float->int conversion slightly to get the full range of negative samples, use clamp to make sure we don't exceed our int range on the positive axis (see also #755301)
