Pack,modify and unpack Android OTA update files

[yoshimo]

Android Update files are not standard archives so all you can see with nanazip are a couple of manifests and metadata. Would be nice if you could use https://github.com/tobyxdd/android-ota-payload-extractor to add full support for these files.

I will try to implement that.
