First of all, great job with this library - the code is well-documented and clear. I was up late last night looking for a good library for manipulating CSS transforms, and was very happy to find this one!

I was wondering if you would be open to the following (small) features? I can definitely help with some of them, let me know if you are willing to accept PRs on any of these.

• b45c121 — Rematrix.toString([...]) for converting a matrix array to a CSS string.

• 574e24e — Rematrix.rotate(...) that defaults to Rematrix.rotateZ(...) (re: CSS spec)

• Something that allows you to specify the unit for rotation, e.g. Rematrix.rotate(0.5, 'rad') perhaps? (Moved to Add unit type to rotation and skew methods #2)

• Decomposition: probably a bigger feature ask, but a way to decompose a matrix and grab specific values such as translateX, skewY, rotateZ, scaleY, etc. from it?

• 0817c2d — Typescript definition file

Thanks so much for this library!
