Create "data GH repos"

We have identified a few data objects that need version control, a version release system and an automated QC flow.
For these objects, we will create new "data repositories" on GH -- being mindful that the individual size of each dataset _must_ be small (under 50MB).

[data object -> repo]

- [ ] BECdb -> **bcgov/SS_ssBC_data** (⭐ in https://github.com/bcgov/CCISS/issues/50)
- [ ] US site series -> **bcgov/SS_ssUS_data** (🔵 in https://github.com/bcgov/CCISS/issues/50)
- [ ] AB site series -> **bcgov/SS_ssAB_data** (➕ in https://github.com/bcgov/CCISS/issues/50)
- [ ] site series table -> **bcgov/SS_feasTables_data** (🔺in https://github.com/bcgov/CCISS/issues/50)
- [ ] edatopic table -> **bcgov/SS_feasTables_data** (🔺in https://github.com/bcgov/CCISS/issues/50)
- [ ] feasibility table -> **bcgov/SS_feasTables_data** (🔺in https://github.com/bcgov/CCISS/issues/50)
- [ ] CF reference guide -> **bcgov/SS_CFRG_data** (💙 in https://github.com/bcgov/CCISS/issues/50)

Start by reviewing issue #50 and the repository mappings listed here. Check the proposed GitHub repositories and confirm how version control, releases, and automated QC should apply to each data object, including the under-50MB constraint. Done means the required data repositories and their agreed workflows are created.
