Moved into GeographicOrigin class following discussion with the working group.

datatypes currently used in the the [termlist](https://github.com/tdwg/cd/blob/review/standard/terms/ltc_standard_terms_draft.csv): https://json-schema.org/draft/2020-12/json-schema-core.html#name-instance-data-model

For discussion at the next WG session (10-11-22): Suggest we re-assess which GeoOrigin terms we're including in the first release: at the moment it's just continent, locality, salinityType, region, waterBody...

Partially addressed by PR #428, but I'm leaving it open until someone reminds me whether ecoRegion (#225) is included or not - the ecoRegion term-level issue isn't tagged with 'done'...

Working Group decision following discussion: Include ecoRegion in first draft, see notes from [30/11/2022](https://docs.google.com/document/d/16RCOisUhdl3h9ZmV2tZFHaRxnzdSfKbQKXKEaFKFAdA/edit#bookmark=id.6olb7lua69x1)

I've made a review branch: https://github.com/tdwg/cd/tree/review 🌳

Ref #379

Decision made in the working group to update the definition of this so it isn't an exact copy of the CIDOC property/is more appropriate for objects incorporating biological part materials.
