Unable to access unsigned data fields from Java

[angusscott]

Currently trying to use the library within a Java project, and have mostly been able to get a basic project working. Problem I have is that the inline UByte class isn't accessible to Java (can't see component1() or getDecimals()). Proposal would be to add Java friendly accessors like below

Additionally, as per the Kotlin guide, you cannot catch Kotlin exceptions, unless a method is annotated with @throws(SuiException::class)

https://kotlinlang.org/docs/java-to-kotlin-interop.html#checked-exceptions

data class SuiCoinMetadata(
    val decimals: UByte,
    val description: String,
    val iconUrl: String?,
    val id: String = "",
    val name: String,
    val symbol: String,
) {
    @JvmName("getDecimalsAsInt")
    fun getDecimalsAsInt(): Int = decimals.toInt()
}
