Models for query parameters

[mo-lukecarr]

Are there any plans to offer Pydantic models for the different query parameters supported by each query resource/type?

In my mind, having models for these query parameters will make it simpler to validate request URLs for query endpoints when implementing an EDR API (for example, FastAPI supports using a single Pydantic model to validate query params).

I'm happy to crack on with implementing this in a PR, but wanted to check in first by raising an issue. Also, I'm slightly confused around the variables.py file. Are these models the same as the query parameters, or a different part of the EDR specification (but confusingly sharing fields with similar names)?
