Start stripping out the actual GroupCompressor
in preparation for using the diff-delta code.
Add some tests that we can generate and apply diff deltas.

We need to start adding some exceptions, and consider moving the
core of the patch-delta loop back into a pure C function, as the
generated code is very messy.
