Optimize for identical images case #60

Closed mourner closed 5 years ago

Closes #38. Closes #39 (being a replacement).

@bontscho I'm very sorry for not getting to your PR in time! Took the same approach but adapted it so that it doesn't rely on Node-specific features, and instead works on typed array level so it works both in Node and the browser. Performance is about the same.

I also opted for doing the optimization by default, without any options — there seems to be no value in turning this off.
