AdbLib fork

[tananaev]

Just want to let you know that I have created a fork of your library:

https://github.com/tananaev/adblib

The main reason is to publish it on maven repository to simplify adding it as a dependency. Had to change package name to match my group id.

Another small thing is addition of an option to provide key pair to crypto class. I use android key store system to generate and store keys, so I needed a way to pass it into adblib.

Thank you very much for open sourcing this project. I started developing some similar first, but then stumbled upon your library and decided to use it.
