Use isArrayOrTypedArray in gl_format_color.js

fixes #2591 - one Array.isArray -> Lib.isArrayOrTypedArray that slipped through in #2388

Nice and easy - 💃

No guarantee there aren't others lingering out there... I wonder if we can do something perhaps in the react-noop tests like crawl each figure for numeric arrays, convert them all to typed arrays, and verify that nothing fails? I guess that wouldn't have caught this one though, as it didn't cause an error, just failed to use the array, and it doesn't seem like there's any generic way to tell that other than I guess image tests...

Or we can just let @jmmease tell us what else we missed 😉

This gets my vote 😄

Or this #913 or probably the best solution from #1784 (comment)
