Though the compression ratio is worse.
But that is partially fixable.
I have to go back on that, due to restrictions in the lz4 spec
many _very_ small files will have significant overhead.

I fear that is going to be pretty slow and will eat at least 1.5

The decompressor is ready to be released.
It should work for all files compressed with the vanilla

I would have to make a special runtime version to archive
