The first release candidate of GMT 6.2.0 has been released (https://github.com/GenericMappingTools/gmt/releases/tag/6.2.0rc1) today.

Now GMT 6.2.0rc1 is available in the devel channel on conda-forge (https://anaconda.org/conda-forge/gmt/) and can be installed using:

conda install -c conda-forge/label/dev gmt=6.2.0rc1

We need to:

• Bump the GMT version to 6.2.0rc1 used in the CI tests (Bump the GMT version to 6.2.0rc1 in CI #1218)
• Some tests fail and we need to fix them
• Add some new tests for upstream bugs that were fixed in 6.2.0rc1
