   • subtypeSchemas: Path or URL to a file that includes the subtype schemas, defaults to https://processes.openeo.org/meta/subtype-schemas.json
   • checkSubtypeSchemas: Enable or disable running checks against the subtype schemas. Defaults to false (disabled).
   • forbidDeprecatedTypes: Set to true to disallow deprecated subtypes such as raster-cube and vector-cube. Defaults to false (disabled).
   • checkProcessLinks: Set to true to validate whether the links to processes in descriptions are valid (i.e. the files exist). Defaults to false (disabled).
   • verbose: Verbose output for tests. Defaults to false (disabled).
