Systematics aware selection in Overlap Removal and Event Scale Factor algorithms
This is a manual sweep of !47106 (merged) to master.
Systematics aware selection in Overlap Removal and Event Scale Factor algorithms. Instead of making view containers one could write systematically varied OR decision (or event-level scale factor) that can be then used downstream or written out to the output.
Can get improved when we have systematics aware selection handles, but it's a good first step.
