Fastapi-cruddy-framework

- Fix README
- Shim openapi json 'where' to be compatible with https://github.com/OpenAPITools

- Update sqlmodel to 0.0.21
- Update internal functions to handle native UUIDs

- Relax `Repository` return types to allow user space typing

- Upgrade base sqlmodel version to 0.0.19

- Adds support for polymorphic relationships, which do not have directly associated foreign keys.

- Adds new exception `CruddyNoMatchingRowException`
- Raises `CruddyNoMatchingRowException` whenever a CRUD operation that looks completely valid based on model validation unexpectedly fails on the database side of the transaction. This is typically due to row-level access control policies implemented in languages like `plpgsql`.
- Added example function to the example sever which adds a global funnel to catch all `CruddyNoMatchingRowException`s and return a 404.
