Need sphinx-tabs

[Richard Shaw]

With upcoming OpenColorIO 2.x the documentation generation system has been
completely overhauled and now has a number of new requirements, including
sphinx-tabs.

I have packaged it although I have been unable to get %check to work. I'm
not sure if it's a PBKAC, missing additional testing deps, or they're
actually failing.

It looks to be a very low maintenance package so my idea was to get the
review request done and get it built in Rawhide and then hand it over to
the sig as I need another package to maintain like I need another hole in
my head.

Thoughts?

Thanks,
Richard
