Mace parities for SO3-restricted symmetry / Use mace-torch weights

Here `p=-1` (by default of `e3nn.Irreps.spherical_harmonics`), however in mace-torch `p=1` (`interaction_irreps` is called `sh_irreps_inter` in mace-torch). It seems that in mace-jax, the author forgot to add `p=1` as well.

```python
if not self.include_pseudotensors:
interaction_irreps = e3nn.Irreps.spherical_harmonics(self.l_max) # so3: 0e+1o+2e+3o+...
else:
interaction_irreps = e3nn.Irreps(e3nn.Irrep.iterator(self.l_max)) # not so3: 0e+0o+1e+1o+2e+2o+3e+3o+...
