Modified the template matching routine so that it works a little faster.
It used to calculate the template matches for the entire file and then
assign labels according to the best matches near syllable onsets. For
large files, this takes a lot of time. So instead now I pull out a short
duration around the syllable onset (anywere between 0.35 and 0.7s long
stretch) and then I calculate template matches only for this section and
then assign labels. For longer files, this makes it about 3 times
faster.
