Make geo-types and geojson optional

[TimTheBig]

This patch makes geo-types and geojson optional so the user can reduce dependencies. They are still enabled by default to prevent breaking changes.

Hi and thank you for your contribution!

It seems the tests are falling because of cargo fmt --all --check, can you run cargo fmt --all and push the changes?

For sure, done

I find that I have to use the geo integration do you think you could add some getters for the inner geometry of a SFCGALGeometry?

Why not? What do you have in mind?
SFCGeometry currently implements the ToCoordinates trait (in addition to the TryInto and ToGeoJSON/FromGeoJSON traits, which convert to/from geo-types and geojson, respectively), which provides a way of retrieving the coordinates of a geometry of the various types supported by SFCGAL (in the form of a CoordSeq).

I'm merging this but let's continue the discussion about your last question, here or on a new issue.

Are the geometry types in sfcgal structs/classes
