V5 optical sensor refresh rate

The optical sensor will send back data to the the brain every 20mS, however, to make the sensor sensitive enough to light the default integration time is 103mS, that means that normally you will see values change approximately every 100mS. The integration time can be changed in VEXcode as necessary, the relevant APIs are.

      /**
       * @brief set sensor integration time
       */
      void            integrationTime( double timeMs );

      /**
       * @brief get sensor integration time
       */
      double          integrationTime();
