/// CHANGELOG: v0.11 (gondola-core): Merges TofEvent, TofEventSummary and 
/// MasterTriggerEvent all into a single TofEvent, based on former TofEventSummary.
/// The new TofEvent has the ability to cary RBEvents and thus mimick the "old" TofEvent
/// We are using the version flag to indicate:
/// * ProtocolVersion::Unknown - The "old" TofEventSummary. (now "TofEvent"). No extra 
///   variables for the GCU, no RBEvents
/// * ProtocolVersion::V1      - The version crafted for Antarctica '24/'25 containing 
///   a bunch of summary variables for the GCU (e.g. nhits(umbrella)). This version will 
///   add these variables to the bytestream and also if ProtocolVersion::V1 is read out 
///   from the bytestream, the variables are expected to be in it. This is to keep compatibility
///   with the gcu
/// * ProtocolVersion::V2     - v0.11 (gondola-core) version of TofEvent(Summary).
///   This version will not write out GCU variables and does not expect them to be in the 
///   bytestream. If desired, this version can read/write RBEvents. 
/// * ProtocolVersion::V3     - the "latest and greatest". This version has gcuvariables 
///                             AND rbevents. RBEvents can be stripped off later on.
