Ecosystem-wide testing

[tiemvanderdeure]

As I proposed in the geospatial community meeting, we could use this package for ecosystem-wide testing.

For example:

• packages do not export the same names (Name overlaps #1)
• conversion between types works (e.g. call Raster on a YAXArray)
• interfaces are correctly implemented (e.g. writing a lazy raster doesn't use chunks rafaqz/Rasters.jl#889)

We don't have to add all of this at once - if an ecosystem-related bug comes we could add a test here and incrementally build a test suite.

It would be nice if we could run @JuliaGeoBot test in a branch of any package and run the Geo tests with the package devved to the branch. So multi-package tests don't all run all the time but so we can check them when a PR is done

Not sure how much work it is to write such a bot

Yeah I've been mulling over this as well, might try it.

That's actually a reverse dependency test bot, those exist for testing new Julia versions, and we really need one for certain jll packages.
