Makie support

[jw3126]

With GeoInterfaceMakie it is possible to give Makie support to LibGEOS in one line:

https://github.com/JuliaGeo/GeoInterface.jl/blob/40af14b80d0620f44a8a9d4063b1f36d36c60ab9/GeoInterfaceMakie/test/runtests.jl#L8

The question is where that line should live. My preference would be to have it right here in LibGEOS.jl. That would
add GeoInterfaceMakie as a dependency which itself depends on the following:

GeoInterface = "1"  # LibGEOS dependency anyway
GeometryBasics = "0.4.4" # neither super lightweight, nor super heavyweight
MakieCore = "0.5.1" # super lightweight

Is that acceptable?

The alternative would be to create a one-line LibGEOSMakie.jl package.

What do people think about these options?

Great that this is possible with one line. What do you think about simply documenting that users need to run this line if they want to plot the geometries with Makie?

Mhh, the call is a macro, that overloads a bunch of methods needed to do Makie plotting. If people need to include this in their scripts or even packages, the macro might be called multiple times and this will yield warnings, recompilation etc.
