ultimate2: 8BitDo controller configuration protocol and Linux client

ultimate2 reconstructs the configuration protocol for supported 8BitDo controllers and implements command-line, graphical and browser clients. Its protocol document reports using REA with Ghidra on a native DLL and ILSpy on .NET assemblies to recover HID reports and configuration records. The clients read, edit and write controller settings.
