docs, typo: chromaloc vs. chromalocs

[Selur]

http://x265.readthedocs.org/en/latest/cli.html?highlight=min-keyint#cmdoption--chromalocs states '--chromalocs', but cli help shows '--chromaloc'

[djcj]

Yes, '--chromaloc' is the correct term: https://bitbucket.org/multicoreware/x265/src/d2db9c1ab44b95e73665037a3f64ea97718e442b/source/x265.cpp?at=stable#cl-192
