Implementation of the DRIVE attribute of IO pads #60

This is a rather comprehensive implementation based on the manual on one side and prjxray on the other side. Without it, it could happen that the output would not work because the drive feature was missing.

Closing this pull request, because the next PR will be based on this one.
