feature request: is it possible to add hardlink unpacking

[carver-ua]

Hello, i am using ubidump.py - for unpacking UBI, all OK, super tools. but one device used hardlink, and it is lost. when I extracted files. therefore, when a new UBI is created, it grows in size. how difficult it is to fix/add ? Thanks.
