Currently tar2ext4.go -vhd only support the creation of fixed sized VHD, is it possible to expand the support to creation of dynamic size VHD?

Research direction
Start with ext4/tar2ext4/tar2ext4.go around the -vhd handling and ext4/tar2ext4/vhdfooter.go around the footer implementation. Trace how fixed-size VHD metadata is built, then determine the additional metadata needed for dynamic-size VHD creation. Done means -vhd can produce a valid dynamic VHD while retaining existing fixed-size behavior.
