LibAudio: Make ResampleHelper templated for different sample types

Browse source 
Previously, ResampleHelper was fixed on handling double's, which makes
it unsuitable for the upcoming FLAC loader that needs to resample
integers. For this reason, ResampleHelper is templated to support
theoretically any type of sample, though only the necessary i32 and
double are templated right now.

The ResampleHelper implementations are moved from WavLoader.cpp to
Buffer.cpp.

This also improves some imports in the WavLoader files.
