Dont compress files under a certain size

[SilverAndro]

The compression dictionary can actually expand the size of certain files

"Dont compress under X" is a quick fix, maybe add an option to properly test each file?

Compress all files like usual, then compare the original to optimized size and pick the smallest one.

That would require me to rewrite the packer I think? Either that or create a dummy ZIP to attempt to pack stuff to first
