Test adding libsodium for crypto stuff

MESON LSP IS THE WORST THING IN THE UNIVERSE AFTER TOMATO JAM.
I tried to nuke this thing already, and it is always back with its bugs where files are not saved, lines are trimmed and it makes reproducing errors a joke.

+At the moment the way `app` is designed is not really great in my opinion.  
+It lacks the ability to properly describe information about it and its distribution.  
+Also, it forces the distribution of an application in multiple files, which might not always be desirable.  
+Even less so if the plan is to distribute them as single executables at some point.  
+So...
