Squashed more bugs, updated NativeMetadataMain.kt so that reachability metadata includes image i/o. This makes the Graal native image actually work when having to convert from webp to png. This will be a non issue when I can find an image library that is written in pure Kotlin.

The last shipwright to review my project tried syncing a mix, which is infinite. So I added an error for that and made sure no one will run into unexplainable errors again.
