[ BUG ] Import issues with transformers > 5

[WardLT]

There appears to be a version conflict with safe and transformers v5.

  File ".../autohyp/molgen/genmol/utils.py", line 6, in <module>
    import safe as sf
          ^^^^^^^^^^^^
  File ".../env/lib/python3.12/site-packages/safe/__init__.py", line 4, in <module>
    from .sample import SAFEDesign
          ^^^^^^^^^^^^^^^^^
  File ".../env/lib/python3.12/site-packages/safe/sample.py", line 17, in <module>
    from transformers.generation import DisjunctiveConstraint, PhrasalConstraint
          ^^^^^^^^^^^^^^^^^
ImportError: cannot import name 'DisjunctiveConstraint' from 'transformers.generation' (.../env/lib/python3.12/site-packages/transformers/generation/__init__.py)

It can be fixed by reducing the transformers version to "transformers<5", and I'd suggest updating the pyproject.toml accordingly. I haven't yet worked out what changes to make to the imports within safe.

@WardLT would you be willing to make a PR that potentially handles transformers>=5 too ?

I should be able to and will keep you posted.
