EventInfo mcChannelNumber AODFix for EVNT-to-EVNT workflow

Matthew Gignac requested to merge matthewgignac/athena:21.2-EventInfoRunNumFix into 21.2

Hi,

This branch implements an AODFix for samples affected by a bug in the EVNT-to-EVNT workflow, whereby the mcChannelNumber from the parent EVNT file is propagated to the output EVNT files in this transform. The fix is expected to run in the AOD->DAOD stage and is only scheduled if the mc_channel_number in input file is in the list of affected samples. The runNumber provided in the DAOD request is used to configure the AODFix algorithm, and uses this to rewrite the EventInfo with the correct mcChannelNumber.

The issue was discussed in this JIRA: https://its.cern.ch/jira/browse/AGENE-1655

Cheers, Matthew
