[LAA] OpenAV Luppp 1.2.1

[Georg Krause]

Good Evening!

I am happy to announce Luppp v1.2.1 in the name of the Luppp Dev Team.

This version brings some minor improvements for the meson build system 
and is now able to print its version number with luppp --version.

Additionally we worked on automated builds and will soon provide 
AppImages, mainly as a demo and for testing. This makes testing easier 
for some needed deep changes on the code base in the next release.
