Test all available geometry sources

[rafaqz]

We should automate testing across geometry types from:

ArchGDAL.jl
LibGEOS.jl
GeoInterface.jl
GeometryBasics.jl
Meshes.jl

Just using GI.convert in a loop over the modules.

And maybe Shapefile,jl and GeoJSON.jl ? These would need write/read to convert, as there is no GI.convert for them as its not very useful except for testing like this.

This would make use of GeometryOps.jl much more robust, avoiding errors like #133

It would also provide some useful tests on the rest of the ecosystems GeoInterface implementations.

https://github.com/JuliaGeo/GeometryOps.jl/blob/main/benchmarks/geometry_providers.jl was meant to benchmark them but it ended up examining only the performance of Shapefile.jl.

It would work as a good base to run the rest, though.

I wrote a macro to wrap all our tests in:

using GeoInterface, ArchGDAL, GeometryBasics, LibGEOS

macro test_all_implementations(args, code)
    args = esc(args)
    quote
        for mod in (GeoInterface, ArchGDAL, GeometryBasics, LibGEOS)
            let ($args = map(g -> GeoInterface.convert(mod, g), $args))
                $code
            end
        end
    end
end

pointa = (1, 2)
pointb = (3, 4)
@test_all_implementations (pointa, pointb) begin 
    # tests here
end
