Static Documentation for v0.1

[brunosan]

This PR expands the current documentation based on #64 and tries to clarify structure.

It does not include executable documentation (Experiments, renamed tutorials) since I don't know yet how we can show the outputs of these without adding execution outputs to the repo history, nor having the CI download and execute the code. I'll PR a solution forking from here.

It also bring over the notebook from branch clay-over-ai.

We should have this merged before Wednesday presentation in Davos.

240105-clay-v0-interpolation.ipynb
240105-clay-v0-reconstruction.ipynb
240105-location-embeddings.ipynb

Currently fail to run. I suspect @srmsoumya made this with a different version of the ClayModule, but I can't track the differences.

Error is:

Yes please make all changes you feel should be done. I can take over later today.
