WavWriter needs a TON of modernization work, but for now this commit just tackles two FIXMEs by converting samples correctly into all supported integer PCM formats. The supported formats are only signed 16-bit and unsigned 8-bit for now, but can be expanded later. At least we don't produce horrible speaker-destroying noise when writing any other format.
