Lots of new functions for wine

Big News! you can now create flasks (aka wine prefixes) they don’t actually show up anywhere or anything and you can’t do anything with them yet…..but it’s a start
I made it keep a small flask.json file inside each prefix to keep track of which wine version created the prefix, which programs should get launched with that prefix, etc, ofc this is just a json encoded instance of the flask struct using swift’s JSONEncode
I wrote functions to launch a .exe from Wine and to scan for created flasks, i just haven’t hooked them up to any UI yet

What’s next

I really really NEED to figure out error handling in SwiftUI apps as i am currently just throwing errors to standard output or straight up ignoring them and returning (which is bad), so i think i won’t work on more backend functions until i learn how to handle errors correctly
And ofc hook the UI up to the wine functions and error handlers and whatnot
Also polish the UI a bit, currently a bit rough
