This implements all of the vector norms (see: https://numpy.org/doc/stable/reference/generated/numpy.linalg.norm.html) and the full corresponding API (i.e. keepdims, axis, and ord arguments).
This also implements the Frobenius and L2 norms for matrices. Matrix norms don't support the axis argument.
Fixes #1273
