v0.1.3

This version includes the following changes:

• Adding two new options to our MACE implementation (see MaceConfig, these features
  should be considered in beta state for now):

  • gate_nodes: bool to apply a scalar node gating after the power expansion
    layer,
  • species_embedding_dim: int | None to optionally encode pairwise node
    species of edges in the convolution block.

  Making use of these options may improve
  inference speed at similar accuracy.

• Fixing a bug where stress predictions would override energy and force predictions
  to None when predict_stress = True. Note that stress computations
  should not be considered reliable for now, and will be fixed in an upcoming
  release.
