new coefficients for the vhq resampler

previous coefficients were provided by a 3rd party and didn't have a
way to re-generate them. we're now using the 'fir' utility.

the performance of the filter is virtually identical, except for
the down-sampling case which seems slightly better now:
   It looks like both the previous and new coefficients are generating
some sort of clipping for full-scale signals in the down-sampling case
(although the new ones seem better), the reason for that is
unknown (see bug: 7453062)

Also updated the HQ coefficients for the down-samplers, previous ones
were a little bit too conservative -- the new ones push the cut-off
frequency up by about 1 KHz.
