Address issue #23. Updated the argparser and the submodules.

Usage: rtdp [-h] [-v] [--log_file LOG_FILE] [--log_level {debug,info,warning,error,critical}] [config_file]

rtdp: JLab's streaming readout RealTime Development and testing Platform.

positional arguments:
  config_file           path to your YAML configuration file

options:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  --log_file LOG_FILE   log file name

Updates:

• Add to arguments log_file and log_level to argparse.
• If not specified, the application would log to rtdp.log. Logs of previous runs would not be overwritten.
• Log level is configurable. By default it's "debug".
