[flac-dev] Higher compression modes from Flake

Flake is a completely independent codebase.  When I used it years ago, I
remember it being not only better compression but significantly faster as
well.  I believe some of the techniques used in libflake were added to
libFLAC in 1.1.4.  However, some of the improved compression in flake was
due to options that are outside the FLAC 'subset', such as larger
blocksize, greater number of prediction coefficients, and higher-order
Rice codes.
