gdal3/proj6 fixes

[sckott]

from kurt

Please see the problems shown on
https://cran.r-project.org/web/checks/check_results_geojsonio.html.

Specifically, see the problems for the Debian check systems.

These are from a recent system upgrade to GDAL 3.

Can you please fix your package to work with both GDAL 3 (and PROJ 6) as
well as GDAL 2 (and PROJ 4), as used for the other check systems?

[sckott]

we're testing now on GH actions with both older and newer gdal/proj setups, all passing

Sorry, with released 0.9-0 still seeing:

as on CRAN. The structure of the sf "crs" object has changed completely. Maybe drop test-crs_convert.R until things stabilize?

[sckott]

Thanks. I'm about to start dealing with this and submit a new version with fixes. I might just drop these tests
