Is your feature request related to a problem? Please describe.
The current AnalysisEpic uses TTreeReader, which is relatively inefficient for reading the data, compared to the features that PODIO Frames provides.
Describe the solution you'd like
Following #271 example macros, update AnalysisEpicPodio from using deprecated EventStore to PODIO Frames. Verify the output is consistent with current AnalysisEpic.
Additional context
This will only work on data produced after eic/EICrecon#578, i.e., production versions 23.4 and newer.
