Updated build process and modified font

- Updated font metadata
- Renamed to Potta One per Google's naming requirements
- Tweaked shape of ogonek form to achieve a more proper proportion
- Swapped lining figures and tabular figures so the correct glyph is used in the OT feature.
- Changed width of nbspace to 400 to align with the standard space.
