Summary0001648: Exported WAV files have corrupted metadata

All WAV files created by OpenMPT, whether through stream export or the sample editor, have corrupted metadata. In my testing, this presented as entirely blank metadata fields, except for the title, which contains garbage data.

Steps To Reproduce
  1. Export a sample or song as WAV.
  2. The exported file has corrupted metadata.
Additional Information

I have only included one test sample (16-bit stereo @ 32kHz) of a test "song", but the metadata corruption seems to happen no matter what the sampling rate, bit depth, or stereo-ness are set to. The actual sample data appears to be intact.
I have included renders of the same song as FLAC (16-bit stereo @ 32kHz, default encoder settings) and Ogg Vorbis (Q5.0 stereo @ 32kHz), which are not affected by metadata corruption.

TagsNo tags attached.
