Cut down dist for static/fonts/SourceSansPro

[bernhardreiter]

Resolving #8 leads to a much bigger dist/static because of the general inclusion of all static/fonts/SourceSansPro-* files.

Inspection in the Browser shows that only some font files are loaded.
This can be potentially cut down to only include the font variants that are really needed.

The general import happens in:

intelmq-fody/src/main.js

Line 7 in fc42706

import 'npm-font-source-sans-pro/source-sans-pro.css'
