During comparison of a different compression algorithms I found this bug: LZO
compression is not working at all in Ark utility. I.e., trying to create
somename.tar.lzo, Ark simply quits.
I have working OpenCL subsystem at my machine, and other algorithms work OK
with Ark while using OpenCL.

Really I am not in any need for lzo compression, just informing.

BTW, the best compression algorithms for my ordinary system are zstd and lzma2
(7Zip). Lzma2 is the best, but sometimes zstd compresses even better. Lzma2 is
not using OpenCL (with 7Z utility).
