Allow to remove entities (for instance ifcDocumentReference and the related association)

[TristanLecallierABIME]

Describe the bug 📝

The situation : I have an ifc with inside an ifcDocumentReference entity and some ifcElements related to it with an ifcRelAssociatesDocument association.
I want to delete the ifcDocumentReference and also the relationship, and then save to ifc.

The issues :

• for deleting the entity I use : await model.setProperties(documentReferenceExpressId, {});
  But this does not delete the entity when I save to ifc (with await propertiesManager.saveToIfc(model, new Uint8Array(originalBuffer));, because setProperties doesn't impact the ifcPropertiesManager.changeMap which is used to edit the ifc inside saveToIfc function.

• for deleting association, there is no function like indexer.removeEntitiesRelation
