first attempt at writing a windowedSincResampler... giving up here...

...i think i will try something different.

This unit is an attempt to create a sample rate conversion utility.
It is an attempt to resample by using bandlimited windowed sinc
interpolation. It's not working.

Instead I'm now thinking I will give up on this approach. (With tweaking
i think it would work.) I will try
- create copy of input buffer.
- bandlimit with a windowed sinc filter.
- resample via a regular interpolation method. (linear or better)
added windowed sinc filter
part way through writing a sinc resampler class.
still trying to implement a windowed sinc resampler....

- still not really working here.
will add this unit as a reference.

it doesn't work and not intended for use.
windowed sinc resampler now working...

...but there is the potential for many!! improvements.
added Audio_DSP unit to copy a few DSP functions.
SaveAudioToFile() now resamples input data to match output sampling rate.
add some information about WAVE_FORMAT_OGG_VORBIS
misc: formatting changes.
added a ChunkDescriptor type.
add support for WaveFormat Extensible PCM and IEEE Float formats. HACK-Y

- this hasn't been tested with many test files yet. I've made a few
  assumptions. There's definitely the possiblity this addition
  contains bugs.
added a check for bit depth support.
modified IsSupportedAudioFileFormat() functions.
