EventSelector modifications for new MC waveform hits

[S81D]

Describe your changes

See PR #329 for more details on why we need to alter downstream tools. For the PMTs,EventSelector assumes MC hits are coming from the MC cluster map. For the new MC waveform tool (#324) the ClusterFinder tool handles the MC hits in an identical fashion to the data hits. We therefore need to adjust some of the logic to allow for this tool to use "data" PMT clusters with MC MRD hits, truth information, etc...

Checklist before submitting your PR

• This PR implements a single change (one new/modified Tool, or a set of changes to implement one new/modified feature)
• This PR alters the minimum number of files to affect this change
• [N/A] If this PR includes a new Tool, a README and minimal demonstration ToolChain is provided
• If a new Tool/ToolChain requires model or configuration files, their paths are not hard-coded, and means of generating those files is described in the readme, with examples provided on /pnfs/annie/persistent
• [N/A] For every new usage, there is a reason the data must be on the heap
• [N/A] For every new there is a delete, unless I explicitly know why (e.g. ROOT or a BoostStore takes ownership)

Additional Material

This PR (just like #329) is dependent on Andrew's new MC waveform tool (#324).
