Add support for GeoJSON

[sharlagelfand]

Adding support for GeoJSON! I think I covered everything (added an example, added geojsonio to suggests, reran codemeta, ran docs, etc). But let me know if I missed anything.

Also, thank you for adding me as an author! ☺️

thanks @sharlagelfand !

I like that you used geojsonio for obvious reasons, but I wonder since sf is already used here, if we just use sf instead? I guess it depends on what kind of data you'd want back. Thoughts?

honestly i don't know much about GeoJSON and just googled packages for it -- used geojsonio for the obvious reason without realizing that sf could handle GeoJSON too! i agree, since sf is already used it makes sense to use that too. i'll update the code.

ps, i'm working on this package hence my sudden ckanr investment 😂 thank you for being so receptive to these changes!

sorry for the messy commits 🙈 rebasing is hard

thanks, looks good. cool about the package (see also #113 and https://github.com/VLucet/rgovcan - also canada)

just one change, can you undo the codemeta.json file cahange, so we can keep the PR focused on the actual changes here

[sharlagelfand]

done, thank you! thanks for linking that package too!
