Add possibility to the HltROBDataProviderSvc to use sub-detector dependent ROS data prefetching
With the additional job option "prefetchSubDetROS" it is possible to specify a list of sub-dedectors and sub-detector groups for which all ROBs in a ROS are prefetched on the first access to the corresponding ROS. Sub-detector identifiers and sub-detector group identifiers according to the eformat document should be used. It is possible to mix on the list sub-detector identifiers and sub-detector group identifiers. Example: The list [ 0x4, 0x5, 0x13, 0x14 ] would initiate whole ROS prefetching for all LAR and TILE ROSes and for the ROSes of the sub-detectors PIXEL_B_LAYER and PIXEL_IBL.
