Collada .dae colors?  #92

Is there a plan to load and display multicolored bodies like the visual meshes in the ur_description package) from Universal Robots?

Probably related to MeshCat.jl/issues/129

Am I just missing something in the examples? I'm using DaeMeshGeometry.from_file() which seems like it's going to construct a geometry object with a _meshfile type that the Javascript is going to convert to a _meshfile_geometry.

Maybe a workaround, like manually constructing a Python Object with a _meshfile_object type instead of a _meshfile type? Maybe I could copy over most of the data from a DaeMeshGeometry?

I've seen the texture loading example in demo.ipynb, but not something regarding parsing the materials and color assignments stored in a Collada file.

I don't want to get too deep into trying to modify the Python side if the JS isn't going to load those colors anyway, so I thought I'd ask.
