Fix crash in DaVinci track refitting from lite clusters due to missing VeloDecodeStatus object
Fix a crash in DaVinci caused by the code that unpacks the packed lite clusters on a track -> full clusters -> lite clusters using data on demand to allow the refitting of tracks where the lite clusters on the tracks are stored. The code was not creating the VeloDecodeStatus object, which is needed by the FastVeloTracking refitter, a specialised version of SiClustersToLite<LHCb::VeloCluster> which does this just for the VELO has been added to SiClustersToLite.icpp. See Jira task LHCBPS-1717
