- allow adjusted and provisional strings in --type controller argument
- allow adjusted, provisional, and definitive strings in _get_url() in TimeseriesFactory
- return appropriate abbreviation for adjusted/provisional data type
- translate adjuste/prvisional to A0 location code in EdgeFactory
- only write out DECBAS for variation/reported data types
- translate adjusted/provisional to A0 location code in IMFJSONWriter.py
