Allow NBT stored in DiskOptimizedClipboards to be written to disk as a compressed byte array at the end of the file (#1745)
* Allow NBT stored in DiskOptimizedClipboards to be written to disk as a compressed byte array at the end of the file * Add some deprecations/javadocs and provide the expected clipboard version on error * Javadoc since tags and add location of clipboard folder to error * Refactor load-from-file method into DOC class * Refactor nbt loading code into separate method in DOC
