KMP Application installed on Windows Machine -> Crash

[bode090]

(For some reason I cannot create a PR)

When a KMP App is installed on a Windows Machine, I got this Exception:

java.nio.file.FileSystemNotFoundException: Provider "jar" not installed
	at java.base/java.nio.file.Path.of(Unknown Source)
	at java.base/java.nio.file.Paths.get(Unknown Source)
	at com.goterl.resourceloader.ResourceLoader.getFileFromFileSystem(ResourceLoader.java:247)
	at com.goterl.resourceloader.ResourceLoader.copyToTempDirectory(ResourceLoader.java:88)
	at com.goterl.resourceloader.SharedLibraryLoader.load(SharedLibraryLoader.java:53)
	at com.goterl.resourceloader.SharedLibraryLoader.load(SharedLibraryLoader.java:47)
	at com.ionspin.kotlin.crypto.LibsodiumInitializer.loadLibrary(LibsodiumInitializer.kt:30)
	at com.ionspin.kotlin.crypto.LibsodiumInitializer.initializeWithCallback(LibsodiumInitializer.kt:58)

The Plugin was unusable for installed Versions of the Client, but was working during development

It seemed that the SharedLibrary Loader was making some trouble loading the Files / Libs correctly when the Application was installed

Here's a Native approach and with that, the installed version of the KMP app was working properly

package com.ionspin.kotlin.crypto

import com.ionspin.kotlin.crypto.GeneralLibsodiumException.Companion.ensureLibsodiumSuccess
import com.sun.jna.Native
import com.sun.jna.Platform
import java.io.File
import java.io.IOException
import java.lang.RuntimeException
import java.nio.file.Files
import java.util.UUID
