This includes several enhancements such as 'Sensible array outputs for pygmt info' (GenericMappingTools/pygmt#575) and 'Allow passing in pandas dataframes to x2sys_cross' (GenericMappingTools/pygmt#591) that will make our crossover analysis work and figure generation easier! Also edited Github Actions workflow to only run Docker build on Pull Requests when ready to review or when review is requested (i.e. not when PR is in draft mode).
