macOS lists fonts such as the ones Microsoft Office installs in
/Library/Fonts/Microsoft (Bookman Old Style, Impact, Georgia, Tahoma, ...) but
their files have nothing in the data fork and no font extension: the fonts are
`sfnt` resources in the resource fork. The font scan only read data forks of
.ttf/.otf/.ttc/.otc files, so those families were never cataloged and a file
using one (an EPS naming BookmanOldStyle-Bold) showed the font as missing.
The scan now catalogs a file with an empty data fork and a resource fork by
the fonts in that fork, and loading reads them the same way. The fork reader
(crates/text/src/suitcase.rs) follows Apple's published resource file format,
caps what a damaged fork can make it read and never panics. macOS only.
Tests: the fork reader on a synthetic fork built around a bundled font,
including truncated and garbage forks; a macOS scan of a suitcase file.
