Added support for external connectors in GDS parser/driver. 

* New: In CRL::GdsDriver, create TEXT record under each external
    Net component. Seems to be the aknoweledged way to signal
    external pins.
* New: In CRL::GdsParser, read TEXT record and create Net and
    external components that are in the same layer and at the
    same position.
