Move GeoInterface.jl to an extension

[rafaqz]

Revives #212 but for more recent changes here

Removing the GeoInterface dependency is actually crucial to simplifying GeoInterface plotting dependencies and Makie 0.24, because currently GeoInterface cant extend anything that depends on GeometryBasics.jl because of the circularity (i.e. it will break precompilation).

(there is some chance there will be circularity between extensions somewhere anyway after this, but lets deal with that later, and avoid the more drastic #260 option for now)

@SimonDanisch this is the start of getting rid of GeoInterfaceMakie.jl ;)

I dropped Julia 1.6 and set the minimum compat to 1.10, so that extensions work

The documenter issue is just xvfb, not this PR:

  DISPLAY=:0 xvfb-run -s '-screen 0 1024x768x24' julia --project=docs docs/make.jl
  shell: /usr/bin/bash -e {0}
  env:
    JULIA_PKG_SERVER: 
    GITHUB_TOKEN: ***
    DOCUMENTER_KEY: 
xvfb-run: error: Xvfb failed to start
Error: Process completed with exit code 1.

I reran the doc build, seems to pass.

Thank you! <3
I guess we want to tag this as a breaking version? Or, now that it's an extension, we can do it in a patch release?
Although I think registrator expects dropping a julia version to be tagged as breaking...

[asinghvi17]

I think registrator should be fine? At least I have never had that experience.

This isn't actually breaking, all the functionality still exists, it's just in an extension now. The only potentially breaking thing might be people using GeometryBasics.GeoInterface but I don't imagine many people were doing that...

And better to do that in a patch release so folks can use older versions of GB on older versions of Julia

[rafaqz]

Yeah, accessing internals like that is their problem. I think this shouldn't be breaking.
