painterResource is too slow on iOS

The MOKO resources version of painterResource is much slower than its JetBrains counterpart. For example,

LazyVerticalGrid {
    repeat(100) {
        item {
            // Too slow, the app freezes as the screen is scrolled
            Image(painterResource(MR.images.someImage))
            // Ok
            Image(painterResource("MR/images/[email protected]"))
        }
    }
}

It seems like retrieving images through UIImage, CGImage, and Skia Image conversions is too slow; why don't we just use the same strategy as in the JVM version (although the resource API is experimental)?

For those who have the same problem, we modified MOKO resources as follows, and it works well. https://github.com/clebrain/moko-resources/blob/2cedf849eadd4be7f86ff7fa4ba2d6606bf15aa9/resources-compose/src/iosMain/kotlin/dev/icerock/moko/resources/compose/ImageResource.kt#L22-L59
