Implement rotors #229
Description
🆙 Improvement proposal
Rotors are an alternative to quaternions to implement rotations in 3D (and beyond). I suggest we implement rotors for that reason. My suggestion would be to add types for BiVectors, and implementing to geometric product. From there, implementing rotors should be straightforward.
Note that there is some overlap with #177 to support typesafe rotations. Once we have rotors implemented, they could be used to represent a typesafe rotation (I believe we should keep the mathematical concept of a rotor separate from its geometric purpose).
