From now, sonarpen aar doesn't contain any prebuilt binaries anymore.
arr will be built along with sonarpen-sdk-cpp process

Beside, I updated license headers for whole project

I'm Phong, a developer from Greenbulb team.
About dex file, it's explained here: https://invent.kde.org/greenblub/sonarpen-sdk-cpp/-/blob/master/dex/README.md?ref_type=heads
Basically, it's only a very small class to listen some events from android framework (Which cannot implemented by jni c++ source code, e.g: View.OnTouchListener ...)
To solve the precompiled class problem, I have 2 ideas:

1. Implement that class in sonarpen-sdk-cpp packages and it will be packaged as jar/aar file (will be used in apk build process)
