publish direct apk download link

[umlaeute]

so with the 2nd lockdown starting tomorrow, I'm also investigating how to get the "Stopp Corona" app on my google-free android.

as i don't see any progress in #3 (i'm not blaming anybody, as i understand it can be tedious with corporate policies and limited human ressources), i would like to re-propose @Peeeep's suggestion from #19 (comment) :

please publish the APK somewhere (outside of a "store") for direct download (website / github / apkmirror / apkpure).
that should be pretty easy to do (e.g. just add an asset to the github release page).
