The DUNE 2x2 and ND uses of larcv produce very large Particle and Interaction IDs (the former because an extremely large number of true particles are simulated; the latter because the interaction ID encodes the GENIE file it came from). In order to store them successfully without wrapping we promote the basic type to be larger.
