enable 4 antenna in scanning

[jeffencillo]

Hi, I've been working on continuous-read.py from example folder and working good so far, everything is working I'm able to update the scanned cards through google spreadsheet. Im using a reader with capable of connecting 4 antenna, however the continous-read.py only works with a single antenna connected to it. Is there a way to tweak on the script so that 4 antennas can work at the same time?

Thank you.
