Turn LSL example into a command line executable python script

[teonbrooks]

@gabrielibagon wrote a pretty cool example. we should simplify it to a simple command line executable so we can do something like this:

npm start openbci
python openbci_lsl

and everything just works

I can help out on getting the python part set up. just wanted to put it out there. will come back to this issue soon

All you need to do is spawn the Python and Node scripts in their own processes, so could be really easy to just have a super script that spawned both children

closing because this is no longer a priority. the example above is adequate
