testing for legendgrams?

[jGaboardi]

@ljwolf Should legendgram/test_legendgram.py be moved into a new tests/ directory?

[ljwolf]

sure; better to be consistent. In theory, I'm fine with having small packages have no dedicated test directory, but there's no reason not to be consistent.

Further, as @martinfleis notes, we need to update the tests. pysal.contrib is over, and we need to use the standard geopandas tools to plot, I think.

• since legendgram is moving to inside splot, should we work on updating the tests once it's in there?
• @slumnitz, are you considering migrating splot testing from TravisCI to GitHub Actions? If yes, I can help out with that.

geoplot from pysal.contrib.viz.mapping isn't even being used in the testing. Can we just remove that import in #11 ?
