F schema export references

Summary

For https://gitlab.indiscale.com/caosdb/customers/dimr/management/-/issues/38 Extends !80 (merged) by treatment of references and list of references.

(List of) References are translated int (arrays of) "oneOf" properties: They include a subschema for the creation of new Records of the referenced types, and an enum with the existing Records. A special case are reference properties with the generic db.REFERENCE datatype. Since here, we can't create a new Record (since we don't know a type), only the enum with all Records and Files is used.

Focus

RecordType treatment has been refactored s.th. it can be used recursively to create subschemas. Apart from this and the generation of the enum values, the existing property treatment was already enough.

Test Environment

Unit and integration tests should be sufficient but feel free to test with your favorite RT from a live system, too.
