(Cleanup) Split js files

[Switch-modder]

All the functions in one .js file was kinda difficult to sift through, so I went ahead and split all the functions into different .js files with names that match their .go files such as wakeword-pv.go being linked to wakeword-pv.js. Now when you need to add a function just make a new .js file under webroot/js/<feature>.js and add the update function if needed under webroot/js/main.js, async function UpdateAllMods().
