smd marking code database and package identification update 210913

The smd marking code data base is updated, to include two- terminal devices, power supervisory circuits, GaAs mmic devices, transient suppression devices. Many typos and redundancies are addressed. Approximately 100K Lines .xlsx format.

The bipolar database is largely unchanged.

A collection of related package drawings with searchable file type names and major dimensions are also available.

This will likely be the last update for these files.

Many web-based resources are available, though their GUIs can be rather inflexible.
