I am typically running calculations on clusters without internet connection on the nodes. Thus, I cannot download MACE models on the fly but have to store them locally.

However, if I do so, this line automatically moves me to "MACECalculator" which does not have the dispersion correction implemented.

I see two options:

• we also add the dispersion correction in a separate calculator
• we somehow add a flag that the model path is from a foundation model and therefore switch to "mace_mp".

@esoteric-ephemera suggestions are welcome
