Logging higher-dimensional arrays with AnyValues does not work, only scalar values per-instance seem to be supported right now.

import numpy as np
import rerun as rr

rr.log("test", 
    rr.Points3D(np.random.rand(100,3)), 
    rr.AnyValues(extra=np.random.rand(100,4))
)

:3: RerunWarning: Converting data for 'extra': ArrowInvalid(only handle 1-dimensional arrays)

Is your feature request related to a problem? Please describe.
Logging the associated ND embedding of a derived 3D embedding, i.e., I would like to inspect the raw, high-dimensional embedding associated with a visualizable low-dimensional embedding.

Describe the solution you'd like
Any values should support lists of arrays, lists of lists, etc.
