lswr: Improve default resampler's default parameters
...
After making some blind tests on a small collection of music
samples for home usage. It turned out that the default cutoff
was too low.
The impact of filter_size was not clearly distinguishable (the
results were on the edge) with the music samples but turned out
to be clearly audible in some synthetic samples.
Thanks to Daniel for helping out with the listening tests.

swr/resample: move templating parameters to template itself.

It has various benefits such as allowing some refactoring, clarifying
the code in the inclusion part, and making the template understandable

This commit is based on the templating method used by Justin Ruggles for
