Free(?) model weights inclusion

[Brendan Tildesley]

I'm looking at packaging openimagedenoise (used by blender). It appears 
to contain model weights[1], which are blobs of numerical data, I assume 
generated from some large corpus of image Intel has on it's servers. The 
weights are licensed permissively, but naturally they are not something 
we can generate from the true source. Are they something that can be 
included in Guix? To me, the "preferred source" of these weights is the 
source code and dataset Intel used to generate the weights, which I 
don't think are published.

If the community isn't bothered by these then I'll include them.
