Include GDAL bin dep in Julia project

[bovine3dom]

Untested.

Should extract this function to a non-PCT specific file and switch to /vsistdout/ to avoid the interim geojson being generated on disk.

Somehow something that worked a few days ago is no longer working

I'm jolly confused.

Edit: comment where it was working - https://github.com/cmcaine/od-vis/pull/1#discussion_r568584421 - I'm wondering if we're using an ancient version of GeoJSON

---

Edit2: yeah, looks like GeoJSON is stuck at version 0.4.0 where the version in od-vis is 0.5.1. Haven't worked out what is forcing it to stay on the previous version

Edit3:

(backend) pkg> add GeoJSON@0.5.1

Seems to work now.

I commented out some broken tests in Turf.jl, but they were broken before I stopped it from depending on exact versions of things.
