Description of the problem

The issue was first reported in GenericMappingTools/gmt#5289 (comment).

The GMT rose module expects length and azimuth.

The sample data @fractures_06.txt contains azimuth,length. When writing the load_fractures_compilation function, we decided to return length,azimuth, rather than azimuth,length, so that the rose tests don't need to swap the columns. However, when writing the tests, we incorrectly used incols=[1, 0], which swaps the columns to azimuth,length again.

The baseline images are correct because the -i option doesn't work as expected due to an upstream bug (fixed in GenericMappingTools/gmt#5289). Thus, after the fix, the incols=[1, 0] parameter is no longer needed.

We need to fix these rose tests after bumping to GMT 6.2.0.
