delta-find: split the _DeltaSearch class in two

We now have things sliced small enough to have two class that use different
`_iter_groups` implementation to encode their different logic.

The filtering code remains to be moved, but I would rather keep this changeset
simple and move them in the next.

ERROR: FIXME: This is a known failure of filelog.size for data starting with \1\n
OK.
