Add name column to extracted data

[smnorris]

Harvesting restrictions mapping requires that the feature name be retained in the cleaned tables. (ie PA_NAME etc).

The column to be retained can be noted by adding a name_column_source or similar to sources.csv. However, retaining this in the cleaned tables would require an additional ST_Union when things get added to the output - there are overlapping features within individual sources (with different names).

Whether the name column is retained could perhaps be a switch in the CONFIG dict. Or it could be the default behaviour - it wouldn't change the conservationlands output, just the intermediate layers which are not currently used.

I have mostly implemented this for generating the "raw" layer (with process --raw) where overlapping polygons are not removed.

@smnorris I think this is also done. Close?

Yep
