Develop infrastructure for internally triggering fragment generation [OtS DAQ]
As we talk with experiments and OtS DAQ colleagues, the value of being able to internally tell some fraction of the BoardReaders to generate a fragment based on data that was previously collected has become clear. (e.g. tell a BoardReader that is reading out slow controls data to send its most recent values).
To prepare for this we, we can add functionality to the EventStore the support the sending of UDP trigger messages to configurable multi-case addresses when new event fragments are received.
