Change so that regions that have lots of copies get converted back
into an insertion.
This does get triggered, but it doesn't help. The total compression is 17MB,
and the conversion time is 10min. Which is equivalent to the original values.
Even further, don't match blocks that are shorter than XX bytes (currently 10).
With a value of 5, we still get trivial blocks inserted. With a value of 10,
everything changes to copies.
Dropping the max block size to 8MB decreases the total bytes to 14MB (presumably
because the copy records now have 1 fewer byte per record). It also makes it 9m versus 10m.
Preferentially splitting based on file-id (at >= 4MB) stays at 9min, but
drops it to 13MB
