Fixed issue with unit tests that was causing raw data to be backwards and reverted related LSB -> MSB change that was introduced due to this. If global palette not set then the background colour index should be 0. Check that background colour index is valid when global palette exists.

This is better solution, because this is allow us check entry count in main cross-ref table and unify loading of main cross-ref table with loading methods of non linearized document.
