F simple schema export

Summary

For https://gitlab.indiscale.com/caosdb/customers/dimr/management/-/issues/37. Export RecordTypes to jsonschema, e.g., for web form generation. Part 1, only primitive datatypes and lists of primitives.

Focus

The main magic is in the construction of the schemas for properties. Also check whether patterns and formats are handled well.

Test Environment

Unit tests should be sufficient, but feel free to test it on the RT of your choice.
