Covbot Enhancements

Features Merged into covbot, a Matrix COVID-19 bot

pwr22/covbot was “a Matrix bot tracking SARS-COV-2 statistics using [public] data”. I added some functionality to this bot by improving its data handling of UK regions and adding a few tabular output forms.

• PR #22 - Scotland – actually added UK-wide regions!
• PR #17 - Tables

These added UK regional data queries as well as tabular output.
