bug#50052: [PATCH] Add prusa-slicer

[Daniel Trujillo Viedma]

Closing this in favor of Ivan's 49713 
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49713), which is more 
complete and advanced than mine.


Thanks to Xinglu Chen and Ivan Gankevich (and everyone interested) for 
their time and their valuable feedback, I learned a lot.


Hope to see you soon with a (hopefully not WIP) new package!


Cheers,

Dani.
