Draft: Add AnalysisHelpers to DaVinci Stack

Update References for: LHCb!4299 (merged), Rec!3665 (merged), Moore!2658 (merged), Alignment!445 (merged), !1013 (merged) based on lhcb-master-mr/11111

OpenData requests require the package AnalysisHelpers that is currently pushed to AnalysisProductions every request. However, this is not ideal since the code is quite stationary. It is probably best make it part of DaVinci alltogether.

See issue 200

Something is not right here. Did you branch off from run2-patches?

Yeah my bad. I went from master. Working on it now
