Stores on desktop targets requires the folder to be created ahead of file writes/reads

[xxfast]

Creating a store for android/ios is fairly straightforward

//android
val filesDir: String = androidContext().filesDir.path
storeOf(file = "$filesDir/countries.json".toPath(), default = emptyList())

// ios
val filesDir: String? = NSFileManager.defaultManager.DocumentDirectory?.relativePath
requireNotNull(filesDir) { "Document directory not found" }
storeOf(file = "$filesDir/countries.json".toPath(), default = emptyList())

However, for desktop we need this extra step

// desktop
val filesDir: String = AppDirsFactory.getInstance()
            .getUserDataDir(PACKAGE_NAME, VERSION, AUTHOR)

FILE_SYSTEM.createDirectories(filesDir.toPath())

storeOf(file = "$filesDir/countries.json".toPath(), default = emptyList())

Need to think of an API to bridge this gap
