This utility is used to parse plist file which is packed by Texture Packer to original images.
usage:
-plist specify the path of plist file(required parameter).
-png specify the path of png file(required parameter).
-dir specify a output directory(optional). By default, it will make a new directory named
with plist filename in current directory to save images.
