SheetJS d7ecca0e8b version bump 0.8.4: formula parsing
- BIFF 2-12 formula parsing
- more content type coverage
- unified `.f` form: A1-style string
- `.F` field for array formulae
- formula output groups array formulae
- bin script -A --arrays output JS row objects
- whitespace robustness in inline string xml
- UTF-8 parsing in rich text runs (fixes #505 h/t @fuchsc)
- bold/italic/underline accept null val attr (h/t @qqilihq)
- sst trimming (fixes #176 h/t @shakhal @oising)
