Monthly Adjust per Station

[dan]

The problem was a typo in README.md.

The plugin was listed as "monthly_adj_per_station".
Changed to " monthly_adjust_per_station". Installation works now.

How could I test this locally?

I think you would need to modify the plugin_manager.py plugin file to point to your fork of the plugins repo on gitHub starting with get_readme() (line 69) and the URLs in install_plugins() (See lines 154 and 166).
