[WIP] BrainAlive Device Integration

[cyberjunk]

@Sarthak301

This replaces your #123

INCLUDE_DEVICE_BRAINALIVE is disabled by default.
Uncomment here to enable:

studio/src/Engine/Config.h

Line 48 in 04e1ff5

//#define INCLUDE_DEVICE_BRAINALIVE

TODO
Engine must not use Qt or code from Studio.
Specifically in Engine/Devices/BrainAlive/BrainAliveNodes.cpp.
This must be refactored at minimum before we can merge:

studio/src/Engine/Devices/BrainAlive/BrainAliveNodes.cpp

Line 33 in 04e1ff5

#include "../../../Studio/Devices/BrainAlive/BrainAliveBluetooth.h"

studio/src/Engine/Devices/BrainAlive/BrainAliveNodes.cpp

Line 168 in 04e1ff5
