• Added asar.ts because can't import original-fs in util.mts
• Updated theme and plugin ipc to use asar.ts when getting addon
• Extracts addons into folder when reading them
• Removes overhead of dealing with asar all together
• Updated installer ipc to delete the addon folder if exists when updating
• Define import.meta.url and globalThis in build script as fix for bundling @electron/asar
• Extracts user dropped addons aswell since it is done when reading them

Would work on all platforms as long as dev plugins work on it.
Closes #373 and #397
