The current default param for the A1 launch files, defaults scan_mode to 'Sensitivity'. This scan mode does not work on the older A1 lidar units.

To correct this behaviour, the launch and view files for the A1 lidar are updated to default to scan_mode 'Standard' which has been to tested to work successfully.
