Update regioning to be more robust and add options to regions such as text and bounding boxes

[Jetsama]

Add options to schematic regioning to give the style of the testbench schematic a more readable and understandable format.

• Allow for named regions in pin types (then allow for specifying region number or automatically assigning a number for region)
• Allow for adding bounding boxes to regions to make separation more clear
• Add region options (such as boxes/notes/sizing)
• Add default region which applies if no options were set for specific region
• Allow for automatic regions for pins (if no region specified for pin, then create new region, with options available for the defaults)
• Allow for regions to specify pintypes (rather than specifying in pintypes section)
• Allow for adding text and notes to each region (using global dictionary)
