Incompatible with Pydantic 2

[prescod]

Any attempt to import DualBaseModel into application code results in:

     testpd.py", line 3, in <module>
    from pydantic_duality import DualBaseModel
  File "site-packages/pydantic_duality/__init__.py", line 22, in <module>
    from pydantic.main import ModelMetaclass
ImportError: cannot import name 'ModelMetaclass' from 'pydantic.main' 

Using:

pydantic                                 2.7.4
pydantic_core                            2.18.4
pydantic-duality                         1.2.0
pydantic-settings                        2.3.2

Yup! I'm adding the compatibility soon but it's not there yet.
