ac25b31ede 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.

stdint.h is for the [u]int*_t types, which is the only thing we need for

don't need here.

Bump micro in case a user app was relying on this include for its own

8ea8833979 swr/resample: move templating parameters to template itself.

This change is required for MSVC DLL builds, as well as avoids accessing a private symbol from another library.

4ec03d1386 bessel: check that the function terminates as expected by av_assert2().
A clear abort is better than wrong output and a possible crash.

1d903a5ee4 lswr: channel_map requires input conversion.
channel_map is applied between in and postin.
Without this test, if the input format is an acceptable internal format,
the in->postin conversion is skipped. In the best case,
it ignores channel_map, in the worst case it causes an assert failure
if the number of channels is changed by the map.
