I've been using this branch successfully with Kotlin 2. The only issue is that it triggers the linter warning "This declaration needs opt-in. Its usage should be marked with '@kotlin.ExperimentalUnsignedTypes' or '@OptIn(kotlin.ExperimentalUnsignedTypes::class)' for the following positions:

6:39, 6:73, 6:78, 7:38, 7:71, 7:76, 8:39, 8:73, 8:78, 9:38, 9:71, 9:76, 11:39, 11:74, 11:79, 12:38, 12:72, 12:77, 13:39, 13:74, 13:79, 14:38, 14:72, 14:77.
