Metadata - Clean function

[Trazi]

I noticed that sometimes optimise (huffman table) function increases filesize instead of making it smaller. There whuld be a way to check if that option actually optimised filesize and if not, optimising whuld be undone and only rest of cleaning options whuld be applied.

Optimise is not to reduce file size, but optimize the huffmann code
