* feat(ps): add craft-ps with an EPS reader (read feature)
The reading half of craft-ps (#115): a clean-room PostScript interpreter
that runs an EPS and returns what it paints as a one-page vector PDF of
its bounding box, colours kept, so apps can draw and export EPS as a
placed PDF. Moved from DesignCraft (storytold/designcraft, where it was
written for placed EPS), with its app-specific names made neutral.
Written from the PostScript Language Reference (3rd ed.), the EPS
specification, the Type 1 Font Format and Adobe TN 5012/5176/5177.
Covers the language, paths, clipping, strokepath, device/Separation/
DeviceN/Indexed/ICCBased/Lab colour, images with lazily decoded filters,
shadings 1-7 and patterns, and Type 1/3/42/CFF/CID text through CMaps,
horizontal and vertical.
Bounded: each operator charges work proportional to its operands
against the step limit as it goes, every byte read or decoded counts,
copies count against the memory cap; defaults 50 M steps / 1 GiB, and
20 M / 256 MiB on wasm32. No panics (deny lints, fuzzed in debug
builds). 34 tests, the Type 42 one on a TrueType font built in the
test. No new external crates: pdf-writer, miniz_oxide, weezl, skrifa
and kurbo are already locked at these versions.

The layer every EPS reader and writer in the apps had its own copy of: where the PostScript
and the previews are behind the binary header (read and write), the header comments with
the bounding boxes (also deferred to the trailer), the EPSI preview bitmap, ASCII85 both
ways, and telling EPS, PostScript and PostScript- or PDF-based Illustrator files apart.
No PostScript interpreter.
