implement first-pass digi mixing for the tracker:
- extend Mu2eProductMixer to include digital data products - implement module for exclusively mixing in such products - propagate those products through to simulated StrawDigi creation - define structure for resolving situations where simulated digis overlap with preexisting digis in time (for now, just choosing the earliest)
