Geometry Overhaul

[JosiahParry]

This PR is a ground up rewrite of the geometry serialization from sf objects to EsriJSON. The current implementation using Rcpp and jsonify is too prone to errors and has been causing a number of headaches. The intent behind this is to use Rust and serde definitions to create geometries in a way that we know will always adhere to the format required. And if not, we will get a (messy) error.

This PR is massive with a lot of duplicative code but its the best I can do for now. It could potentially be simplified using a number of macros.

Additionally the functions as_featureset(), as_esri_featureset() and as_features() and as_esri_features() have a lot of duplicative checking that can probably be simplified into a couple of helpers.

This closes https://github.com/R-ArcGIS/arcgislayers/issues/184

TODO:

• [x] document as_esri_geometry()
• [x] document as_features() and as_esri_features()
• [x] document as_featureset() and as_esri_featureset()
• [x] write examples for all geometry functions. These will act as the tests as they will be executed in R CMD check
• [x] Update NEWS.md
  • [x] note that as_geometry() is deprecated
  • [x] check to see if arguments have changed
• [x] Update README with note about installing from source. suggest using r-universe for development versions

There is an issue with windows CI on 4.1 where core rust library is not being installed.

I have tested publishing with this but still needs more testing for

• Point
• MultiPoint
• LineString
• MultiLineString
• Polygon
• MultiPolygon

to be very sure that it works. But I am comfortable with merging this in.

Once {arcgisgeocode} is done, we will adjust arcgisutils to use vendored dependencies and then publish the new packages.
