Export UUID in the compat module

[angelsenra]

First of all thank you for this great package.

I had an issue at first when trying to use this with pydantic:

pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'uuid_utils.UUID'>. Set `arbitrary_types_allowed=True` in the model_config to ignore this error or implement `__get_pydantic_core_schema__` on your type to fully support it.

If you got this error by calling handler(<some type>) within `__get_pydantic_core_schema__` then you likely need to call `handler.generate_schema(<some type>)` since we do not call `__get_pydantic_core_schema__` on `<some type>` otherwise to avoid infinite recursion.

For further information visit https://errors.pydantic.dev/2.7/u/schema-for-unknown-type

I was going to suggest adding support for __get_pydantic_core_schema__ but then I saw #32 and thought it best to just use the compat version.

However, the compat package doesn't export UUID like the normal one. That's what this PR adds. So one can do import uuid_utils.compat as uuid and act as if it was the built-in uuid.

There are other exports in the main __all__ that are also missing (namespaces, reserved, and getnode). Those I've never used but I would see the point in exporting the exact same list.
