As well as the python workers diffbrowsers and previews.

They use the same tool and mostly similar code.
A family may have new fonts e.g. newly added weights and should therefore have previews for new fonts and the full diffs for updated/existing fonts.
Thus, a completely new family without any existing "before" fonts should produce just previews with the same tool.

Related: #119 and #120, both would benefit from this.

This is also a good maintenance effort as it reduces lines of code and very similar code.
