Add color correction benchmark - with comparison to qcms

--colorImages is empty by default so this won't affect the runtime of
the bots.  To run locally, use --colorImages <path> and
--benchType skcolorcodec.

Two takeaways so far:
Color correction is (currently) slower than jpeg decodes.
Our reference solution is slower than qcms.
