Allow to disable console output

[stefaneidelloth]

What's the problem this feature will solve?
Do not output messages like {"type":"get_step","step":30} to console

Describe the solution you'd like
Allow to influence the output using log level. I tried to use following settings but they did not help to avoid the output of
SocketHandler of ModularVisualization class from self.write_message(self.viz_state_message):

meza_viz_logger = logging.getLogger("mesa_viz_tornado.ModularVisualization")
meza_viz_logger.setLevel(logging.WARNING)

tornado_logger = logging.getLogger("tornado")
tornado_logger.setLevel(logging.WARNING)
