Brother MFC-J430W protocol wrapper (wifi scanner)

Reasons

Brother MFC-J430W has already scanner driver and you can download here but that are prebuilt binary (x86/x64) and source code isn't public. My problem was that I wanted use scanner in my RPi4 but those driver not works on ARM architecture. In the end I solved this issue throught workaround using a vps... recently I resumed the project and I found a solution (partially thanks to this) and imho I think this is better than any workaround.

Scanner protocol

Documentation work in progress....
