suggestion: no_std support

[jimmyff]

Hey, I'd like to use this to make playdate games, but that would require no_std support. It would be great to be able to use this on platforms and devices that don't have access to the standard library.

I see there is a dependency on nalgebra, I belive that weould need default features disabling, not sure about the other dependecies.

Hi @jimmyff !
That sounds like a great thing to support. I do not have the time to investigate this personally right now, but a PR would be very welcome.
