metatensor-torch v0.5.2

This is a patch release of metatensor-torch, containing the following changes:

Added

• MetatensorAtomisticModel.save() to save a wrapped model to a file.
• TensorBlock.__len__ and TensorBlock.shape, which return the length and shape of the values in the block respectively (#640)
• metatensor.torch.atomistic.ase_calculator.MetatensorCalculator can now use vesin for faster neighbor list calculations (#659)
• When running atomistic models in the PyTorch profiler, different sections of the code now have meaningful names

Deprecated

• MetatensorAtomisticModel.export() is deprecated in favor of MetatensorAtomisticModel.save()

Fixed

• metatensor.torch.atomistic.ase_calculator.MetatensorCalculator uses the right device when computing stress/virial (#660)
