arnav-hiwarkar e2e3413011 #3087: an item made from one Photoshop layer shows that layer
Footage made from one layer of a layered .psd showed the whole document and
was named after the file. Its opti (tag 8BPS) stores the layer: the record
index (BE i32 at 14, -1 for the merged image), the bounds (LE i32 at 78-93)
and the name (UTF-8 at 344). The item now shows that layer as EffectCraft's
own Photoshop import does (at its own size with Retain Layer Sizes), named
<layer>/<file>. A layer without pixels (an adjustment layer) keeps the merged
image and is reported.

//! After Effects project (`.aep`) container reader and writer.
//!
//! An `.aep` is a `RIFX` container (big-endian RIFF) with form type `Egg!`. This crate reads it
//! into a lossless chunk tree ([`AepFile`]) and writes it back byte for byte. The XML form of a
//! project (`.aepx`) is read into the same tree by [`read_aepx`]; [`parse_any`] picks the reader
//! by content. See
//! `docs/aep-format.md` for the observed format and how it was established (clean room: only
//! files we generated ourselves, one change per file).
//!
//! [`Project::new`] opens a typed, read-only view over the tree: items, compositions
//! ([`CompHeader`]), layers ([`LayerHeader`], [`Transform`], effects, masks, text documents,
//! markers), properties, keyframes and footage. Only fields whose layout was verified against the
//! values the test files were made with are decoded; every accessor returns `None` (or an empty
//! list) on damaged data instead of failing.
