Set the minimum supported python version to 3.12#141

3.11 is nearly outside the support window for much of the pydata stack and 3.12 will allow pydantic to have full compatibility with `typing.TypedDict`, which one of our dependencies (`zarr-cm`) uses extensively.

Python 3.12 introduces large changes to how type annotations work, such as allowing generic functions and classes to use a new syntax for declaring their type parameters. There are also some new features from typing_extensions, such as the `Sentinel` type. This commit updates the codebase to use these new features correctly, which allows CI to pass.
