Arguments to atan2 are reversed

[aletheos]

hump/vector.lua

Line 118 in 08937cc

return new(atan2(self.x, self.y), self:len())

Typically the arguments to atan2 are y first, and that is how it's done in the corresponding function in vector-light, so I assume this is a mistake.

Hey aletheos, vrld isn't maintaining this anymore. I'm taking care of their repo here: https://github.com/HDictus/hump/

This does look like a mistake, though I'm surprised no issue has come up before with users of hump.vector.
