PySolFC 2.6.4-1 available in Salsa, fixing RC bug

[Juhani Numminen <juhaninumminen0@gmail.com>]

Hi,

I'm monitoring the Debian release-critical bugs list (https://udd.debian.org/bugs/)
and a couple days ago I found out that there's one in pysolfc, which
according to its reporter is fixed in the upstream version (#931851).

Since there was relatively recent git activity, and I too am a member of
the games team, I have updated the package at https://salsa.debian.org/games-team/pysolfc.

Hugo, do you have the time to check out my work and do the upload?
If not, I'll try to seek another sponsor.

Regards,
Juhani
