enable multiple profiles at once

[pvgenuchten]

Currently you have to set a profile (opgapi-records, mcf, datapackage) in settings. Instead would be nice to load the relevant schema file when a new file is created or imported.

• New record -> Select profile -> Load schema -> Open editor
• Open record -> Detect schema of the record -> load schema -> Open editor
• Export record -> dedicated exports for schema's (datapackage and ogc-api:records are based on json, mcf is yml).
