Pydantic integration with custom base class

[dokempf]

pydantic exports JSONSchemas for their data structures. We could provide a custom base class as a drop-in replacement for pydantic users that allows them to automatically configure objects through ipywidgets. In order to have this integration robust, we should:

• Collect a large test suite of pydantic schemas
• Implement all the parts of the JSONSchema specification that are typically used in there (e.g. Implement prefixItems rule #95 , Implement additionalProperties rule to allow non-fixed keys #96)
