PhotoCraft's `photocraft-psd` crate (crates/psd at storytold/photocraft 63b641b55e54bf8f5c83efd977fdb16a2c255431) as `craft-psd`: the lossless PSD/PSB model, reader, writer and builder, descriptors, the Photoshop resource files that share its primitives (.abr, .asl, .aco, .act, .ase, .grd, .pat, .atn, .csh, .shc) and the Photoshop blocks of a layered TIFF. The crate had no dependency on any other PhotoCraft crate. Code is unchanged apart from the crate name, craft-libs' rustfmt width, comments that named other PhotoCraft crates, issue references (now `photocraft#N`), and the corpus tests' directory (`CRAFT_PSD_CORPUS` or `corpus/` at the workspace root). Tests, proptests, fuzz targets and fixtures move with it. Part of #778, #786.
