unpack/repack of vbmeta.img doesn't work

[Tkkg1994]

Hey :)

I've successfully unpacked my vbmeta.img and also repacked it. But one thing doesn't work:

As soon as you set algorithm_type = 0 you'll get this issue:

> Task :packClear FAILED
Exception in thread "main" java.io.IOException: Is a directory

* What went wrong:
Execution failed for task ':packClear'.
> Process 'command '/usr/lib/jvm/java-8-openjdk-amd64/bin/java'' finished with non-zero exit value 1

Everything else works perfectly fine

Hi Tkkg1994,
I submitted a fix for this:

fix issue #3: packing error when "algorithm_type = 0"

Please have a try with latest 'master' branch.
