Any de/compressor support

[Adam Tuja]

Would it be too much to ask for free compressor support? By free, I mean any defined in zutils config file in the way it is now:
For example:
--
# gzip
gz = pigz -p2
# my own super duper compressor
moc = moczip

--

Where `moczip' is my own compressor and `moc' is the extension it uses.

It would be required for decompressor to understand `-d' as `decompress' and `-c' as `to-stdout' options, as mandated by tar.
It would solve all the future requests for another fancy compressor support - could be solved by adding de/compressor to the config file.

There is a prospect it would simplify the program usage as a whole as well.
