Review dependencies for development

[kkappler]

Here is a list of some packages not in the requirements that we may want to put in requirements-dev

• [ ] hvplot
• [ ] geoviews
• [ ] vega_datasets
• [ ] pydataset
• [ ] *N.B. for geoviews I had to first conda install --channel conda-forge cartopy to get around the error

  GEOS version 3.6.2 is installed, but cartopy requires at least version 3.7.2.

See https://stackoverflow.com/questions/53697814/using-pip-install-to-install-cartopy-but-missing-proj-version-at-least-4-9-0 & https://github.com/SciTools/cartopy/issues/1239

The way to deal with is to create a new environment and see what dependencies pop up.

An environment.yml would be a good way to manage this.
