Added STAR WARS™ Galactic Battlegrounds Saga (356500)

I have based this on my (tested) gist.

But as soldier_protonfixify seems to be broken with (at least) version 0.20220131.0 of soldier I'm not sure how to test. I tried to fix the line 11 by applying this patch

diff --git a/scripts/soldier_protonfixify b/scripts/soldier_protonfixify

but unfortunately this seems not to be enough.
