FDC emulation triggered by MWPC raw mode data

[nsjarvis]

When Df125windowrawdata for rocid > 30 is present, without an FDC pulse, the software generates an emulated FDC pulse.

@faustus123 suggested to use the translation table to avoid the hard-wired numbers:

vector<const DTranslationTable *> ttab;
loop->Get(ttab);
if( ! ttab.empty() ){
 auto rocid_by_system = ttab[0]->Get_ROCID_By_System();
 if( rocid_by_system[ DTranslationTable::CDC ].count( rocid ) != 0 ){
  // This rocid belongs to the CDC
 }
}

Is there a data file I can use to test this?

Elton was using this:

Looks good now. Thanks.
