Better to remind the users who still use the ROS indigo. Using the same version of system python to setup and run the driver.

Better to remind the users who still use the ROS indigo.
The Python version of the system is confused, which leads to the lack of the module to be used. The python file in the "../nmea_navsat_driver folder/scripts" starts with #! /usr/bin/python3. but system is using python2.7 for setup. It may pop-up an error "No module named "_tf2"" in ROS indigo.
If we setup the driver in ROS indigo better changing to:
#! /usr/bin/python2.7

-- coding utf-8 --

for those python file in "../nmea_navsat_driver folder/scripts" folder.
