Support for lzo format would be nice addition.

Actually, it seems LZO uses a pretty large number of different algorithms. Understanding
and implementing them all from scratch would be way too much work for such an uncommon
format, so it seems unlikely this will ever be done unless someone else re-implements
them under a more appropriate license. I doubt the original author will re-license
it, since it seems to be GPL mainly to prevent wide usage at the expense of the commercial
version.

I've looked at that in the past, but as the library is GPL I can not include it.

It would require implementation from scratch, which is certainly possible but as it
is not widely used it has not been a high priority.
