v0.8.7

This release benefited from 5 contributors (@DanCodigaMWRA, @flynnpc, @joejoezz, @mroberge, @rhroberts). See Milestone 0.8.7. It focused primarily on two improvements:

1. Added new NOAA GOES reader for GOES DSC/DCP data ingest. This new reader replaces the USGS EDDN reader, which is no longer functional (web service is inaccessible) and was removed in this release.
2. Overhauled the dependencies (requirements files) and test and continuous integration (CI) infrastructure to enable support for more recent Python 3 versions (3.7, 3.8 and 3.9) and reestablish the CI tests. Previously only 3.6 was supported, due to dependency pinning that was no longer necessary.
