ConR vulnerable to forthcoming changes in sp and rgdal

[rsbivand]

Running revdep checks for current rgdal on R-Forge - see:

https://stat.ethz.ch/pipermail/r-sig-geo/2019-November/027801.html

shows the errors in test errors below, related to use of PROJ&/GDAL3
and required changes to sp and rgdal. If useful find a regerence to a docker
image in this thread:

r-spatial/discuss#28

Changes will occur quite fast, and packages need to be prepared.
