[PATCH] Add support for Geopackage in plugin OpenData

[tomasmarklund]

The Swedish equivalent to "department of transportation" has declared that they will drop support for ESRI Shape files at the end of 2022. Instead, they will only provide data as "Geopackage" as from 2023-01-01

Yes, there are (external) online converters from Geopackage to Shape available, but it would be better if the plugin OpenData (or some other plugin) had the support for Geopackage file format directly, without having to convert file formats externally first.

OpenData uses geotools. We would probably have to add gt-geopkg to geotools, and we would need to hook it up to JOSM.

yep

Geopackage is also the only format supported by other public organizations such as Statistics Sweden.

Sorry about the mail churn -- for whatever reason, my IDE was adding files to the patch that it wasn't showing me. Probably due to an interaction between svn and git, if I had to make a guess.

Anyway, I'm going to give @Don-vip a week or two to look at the changes if he wants to, and then I'll apply the patch.

Hi Taylor,
Thank you! I agree with the patch you can apply it :)

No problem -- I know you aren't terribly active right now, but I did want to give you a chance to approve/disapprove of a partial refactor of opendata since you were the primary contributor to it.

Fix #22179: Add support for GeoPackage in OpenData

This does two things:

1. Add gt-geopkg to the GeoTools plugin and update the GeoTools version to 27.1
2. Adds support int OpenData for GeoPackage. This involved a refactor to make it easier to reuse code between the shapefile support and geopackage. As such, it should be much easier to add additional formats supported by GeoTools in the future, if needed.

For whatever reason, the IDE didn't add the new files even though the UI
indicated it would.
