Brainflow support

Hi Teunis,

Have you considered adding Brainflow support? It would allow a wide range of devices to use EDFbrowser for live signal viewing. Brainflow is also being actively developed. https://brainflow.readthedocs.io/en/stable/index.html

At the moment I use a FreeEEG32 board, and through a java based BDFrecorder I use the 'open stream' function in EDFbrowser to view live EEG signals. Brainflow could really add a lot of functionality, and many other EEG amplifiers.

Would love to hear your thoughts on this.

Cheers, Bernard
