Protocol implementation for the SDK

## The ArDrone Protocol

Implementation of the Protocol is hard and messy and this the reason this issue exist - to help and track the protocol implementation for the SDK
Here are some resources and todos (work in progress) that need to be completed to have a fully capable SDK that understand the Protocol of the drones completely

### Resources

- BufferIDs: https://github.com/Parrot-Developers/arsdk-ng/blob/master/libarsdk/src/arsdk_transport_ids.h
- SDK3 (official) C SDK - https://developer.parrot.com/docs/SDK3/#go-deeper
must be built in order to have the reference Features to be able to track them down.
- XML reference of all commands & values - https://github.com/Parrot-Developers/arsdk-xml
- PyParrot (unofficial) Python SDK - https://github.com/amymcgovern/pyparrot
- Android - https://github.com/Parrot-Developers/groundsdk-android
- Concepts (useful for tracking and impl features): https://github.com/Parrot-Developers/groundsdk-android/blob/master/doc/concepts.rst

#### https://github.com/elpiel/arsdk-java-generated/
Generated JAVA code from the https://github.com/Parrot-Developers/groundsdk-android repository + some information on how to generate it
Includes references from the `arsdk-xml` repository generated into Java classes of the `Feature`s and the Protocol in general.
