Add a metadata block for RIFF WAVE subchunks, and
support in flac by way of an option to encode/decode
instead of ignore them.

On the encode side, the wave reader will have to parse
the entire wave file, collect all the non-'data'
subchunks into FLAC metadata blocks (including their
order) and pass to the encoder.

On the decoder side the reverse will need to happen.

Fixup of the subchunks should go in the new FileEncoder. (?)

This could be done by abusing the APPLICATION metadata block
with RIFF (or WAVE) as the identifier. The position of the 'data'
subchunk in the original WAVE file could be preserved by placing
an empty RIFF metadata block which simply contains the 4 bytes:
'data'

The same would work for AIFF, using AIFF as the APPLICATION
and SSND as the metadata placeholder for the sound data.

Uh, that was me what suggested the APPLICATION solution (a
hack, I'll agree) and similar support for AIFF as WAVE.
