ReadLayer now opens the file and streams bytes directly into a T[] for blittable structs to avoid an extra intermediate byte[] allocation. It uses MemoryMarshal.AsBytes and RuntimeHelpers.IsReferenceOrContainsReferences to choose the fast path, handles zero-length files, and falls back to the original ReadAllBytes->ToArray<T>() logic when the file size isn't a sizeof(T) multiple, the type contains references, or a partial read occurs. Added necessary using directives. Keeps behavior compatible while reducing allocations for raw binary layer files. Co-Authored-By: Copilot <198982749+Copilot@users.noreply.github.com>
