Use the DATATYPE for LAYER record in GdsStream. 

* Change: In GdsStream::_gdsLayerTable, use a map<> instead of a vector<>,
    use a combined value of the layer index and the datatype as index.
        (index = (layer<<16) + datatype.
    This allow for layers that are represented by a pair of (layer,datatype)
    with same layer and different datatypes.
* Change: In GdsStream::gdsToLayer(), now have two parameters, the layer
    and the datatype.
