The "Write Wav" button now lets the user download the resulting wav file
on web. Sadly, we cannot directly get a PackedByteArray from
AudioStreamWAV - the WAV header is only written as part of its
save_to_wav() method, which only accepts a string to a file and does all
the file handling itself. Therefore we now write the file to (temp)
disk, re-read it and then send it to the user. The other options I
currently see are a) to write the WAV header myself b) find a better way
to write a tempfile (at least tempfile naming seems to be a Godot >4.3
feature) or c) to contribute a get_wav_header() method AudioStreamWAV
upstream.
The "standardized" mimetype for wav seems to be audio/vnd.wave and not
audio/wav - I never knew! Many seem to point to RFC2361 regarding to
this.
