The output type of some operations should be mainly `QuatRotation`

[hyrodium]

With the current implementation, the output types of some operations such as * are inconsistent.

RotMatrix3 is the most used return type, but I think this should be QuatRotation because it is more efficient.
However, I am not sure we would like to have *(::RotMatrix, ::RodriguesVec) is RotMatrix or QuatRotation. (x-ref: #190)

This issue is not just about the multiplication *, but also includes other operations such as /, ^, sqrt(#234) etc.
