ES missing branch coverage in CFE_ES_RegisterCDSEx, IsNewEntry can't be true without IsNewOffset being true

Is your feature request related to a problem? Please describe.
Branches aren't independent, since a new entry will always have a new offset (can't hit false IsNewOffset with true IsNewEntry):

     432 [ +  + ][ +  + ]:         12 :         if (Status == CFE_SUCCESS && (IsNewOffset || IsNewEntry))
                 [ -  + ]
     433                 :            :         {
     434                 :            :             /* If we succeeded at creating a CDS, save updated registry in the CDS */
     435                 :          6 :             RegUpdateStatus = CFE_ES_UpdateCDSRegistry();
     436                 :            :         }

here:

cFE/modules/es/fsw/src/cfe_es_cds.c

Lines 432 to 436 in e5d4ed9

	if (Status == CFE_SUCCESS && (IsNewOffset || IsNewEntry))
	{
	/* If we succeeded at creating a CDS, save updated registry in the CDS */
	RegUpdateStatus = CFE_ES_UpdateCDSRegistry();
	}
