Allow saving reference file as a float32 WAV file

Allow saving reference file as a float32 WAV file

Update the osccilator sweep tests to save the reference file as a
32-bit float WAV result and also update the expected result with this
new file.  The test thresholds are also updated with tighter values,
and we no longer have to deal with the 16-bit aspect of the original
reference files.
