Possible bug in korio: cannot uncompress valid GZIP file

[MinmoTech]

Hey!

I have an sqlite database that was gzip compressed with korio, but when uncompressing it with korio I get the following error:

com.soywiz.korio.lang.InvalidOperationException: Size doesn't match SIZE(0x00040000 != 0x008A5ECD) || CRC32(0x8A5ECD41 != 0x41000400)

The file tests as valid with gzip on the commandline and after decompressing with gzip the database is indeed perfectly fine.

This is a minimal reproducible example and I also attached the file in question:

import com.soywiz.korio.compression.deflate.GZIP
import com.soywiz.korio.compression.uncompress
import java.io.File

fun main(args: Array<String>) {

    println("Hello World!")
    val compressedDBByteArray = File("test.db.gz").inputStream().readBytes()
    val uncompressedDBByteArray = compressedDBByteArray.uncompress(GZIP)


}

test.db.gz
