Testing results for PLB

- Timings updated to have 15sec Load Balance across the board.
- Timings samples updated for LB_SC_QUERYTIME parameter which was missing in some.
- CRTDSAdapter has endian swap fix applied.
- Loadbalance.cpp has been updated to only operate when dgi-enable is set. This required the DGI to send commands to the RTDS while the RTDS has the dgi disabled, but the commands should only hold the current value. This was to prevent an issue where a 0 value would be read by the RTDS when the DGI was enabled, because no commands had been sent from the DGI to the RTDS.
