Missing announces/refersTo LotGroup under ND-LotsGroup

[schivmeister]

Problem

The relations epo:refersToLotGroup and epo:announcesLotGroup are currently missing in the technical mapping.

Potential Fix

Similar to what has been done for roles, notices should either announce or refer to the epo:LotGroup depending on the subtype of the notice. This would result in assertions like the following:

epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Notice a epo:CompetitionNotice, epo:Notice, epo:Notice16;
  epo:announcesLot epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Lot_LOT-0001, epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Lot_LOT-0002;
+ epo:announcesLotGroup epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_LotGroup_GLO-0001;
  epo:announcesProcedure epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Procedure_MnX8qyREnFMNLeS5MJAX9K;
  epo:announcesRole epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Buyer_HGvue6GtAm3yppLpDLnBKD,

Or:

   epo:refersToLot epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Lot_LOT-0001, epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Lot_LOT-0002;
+  epo:refersToLotGroup epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_LotGroup_GLO-0001;
   epo:refersToPrevious epd:id_9c0fd704-64d3-4294-a3b6-6df45911ab9f-01_Notice;
   epo:refersToProcedure epd:id_14549263-b47b-4e59-96a1-2d0d13e19343_Procedure_MnX8qyREnFMNLeS5MJAX9K;

The correct predicate for each Notice would be similar to what we have for epo:Lot according to the table at the OP-TED/ePO#781 discussion.
