GeoPackage divide_id attribute hotfix

[mattw-nws]

HF pre-release files actually use a different schema and different ID attribute for divides, this PR makes that version work properly for GPKG files. The new format in geojson representation is not fixed. This may break older GPKG formats, but tries to leave them working--no guarantees. Going forward GPKG format is only intended to support the latest HF formats.

Additions

• Can now pass an id_col when reading features table from GPKG, some probing tries to guess which to pass for the divides layer.

Code otherwise looks reasonable to me.

I finally validated that the updated sample dataset included here does work with routing, so this is ready to go. I noticed that I omitted some deletions however. @PhilMiller or @hellkite500 can you re-approve? Thanks.

Merging--failing test waiting on NOAA-OWP/t-route#645 .
