New Features

Added ability to open and import WOFF2 fonts (files are converted to OTF during import)
Added ability to view font PANOSE information in Font Properties window

Updates

Improved loading performance of system font set by 60%-90% by refactoring loading and lazy loading certain things (for example, Win2D CanvasFontFace are no longer created for each font at start up, but delayed until the Font is actual displayed in the character map - properties needed for startup are loaded direct from IDWriteFont)
Reduced startup memory usage
Updated store listing. Perhaps if there's space in the keywords section WOFF and WOFF2 could be added as keywords.
Convert collections to load from a single SQLite database rather than a single filesystem file per collection. This improves collection loading performance (and should be resistant to file corruption)
