replaced SICK S300 driver by the BRICS OODL SICK S300 driver (now runs with 12Hz)

Dear All,
Jan updated the SICK S300 driver with the BRICS OODL SICK S300 driver. With the new driver your are able to run the S300 at 12Hz instead of 5Hz. The frequency with which the scans are published can be set as parameter (e.g. by a launch or yaml file). By default it runs with 12Hz.

There was also a minor change in the test script of the cob_light package.
