Support for 'mps' device (i.e. for Apple Silicon)

[brndnsy]

It would be great if the model would support Apple Silicon devices so that the 'mps' device could be used as follows: model = TabPFNClassifier(device='mps', N_ensemble_configurations=16)

Sorry, that we never replied for this! We'll keep it in mind, but unfortunately have a lot to do. If you'd like to create a PR for this, would be welcome :)

I get an error that MPS device does not support 64-bit floats
