Added
- `GDPR_API_URL_PATTERN` setting for configuring the GDPR API URL pattern.
- `GDPR_API_MODEL_LOOKUP` setting for configuring how the GDPR model instance is found.
- `GDPR_API_USER_PROVIDER` setting for configuring how to obtain a `User` instance from the GDPR model instance.
- `GDPR_API_DELETER` setting for configuring how data deletion is performed.
Changed
- Respond with a `204 No Content` status code when no data is found for the requested profile.
Removed
- Support for Python 3.6
- `helsinki_gdpr.views.DeletionNotAllowed` exception class. Raising that exception produced responses with
contents that are against the GDPR API specification. A user specified function configured with the
`GDPR_API_DELETER` setting should be used instead.
