Retune FLAC compression levels
This patch changes a the settings associated with compression
levels 6, 7 and 8. With this patch, -e is no longer used, but
instead apodization functions are added. This should improve
compression with at least 95% of all material while not changing
the speed much. Decoding ways, 6 and 8 stay the same, and 7 is
slowed a bit, which makes it as fast as 8.
