Describe the bug

A crash occurs when reading certain PSD files. Looks like it's due to RLE encoding... PR incoming

OpenImageIO version and dependencies

Two versions were tested:

OIIO 2.5.11.0 | unknown arch?
    Build compiler: MSVS 1929 | C++14/199711
    HW features enabled at build: sse2

And

OIIO 3.1.0.0dev | unknown arch?
    Build compiler: MSVS 1943 | C++17/199711
    HW features enabled at build: sse2,sse3,ssse3,sse41,sse42,avx,avx2

To Reproduce

Steps to reproduce the behavior:

  1. Try reading the attached file using OIIO
  2. Crash inside PSDInput::read_native_scanline

Python repro

import OpenImageIO as oiio
inp = oiio.ImageInput.open("psd-test.psd")

spec = inp.spec()
nchannels = spec.nchannels
pixels = inp.read_image(0, 0, 0, nchannels, "float")  # does not matter if uint16 or uint8 is attempted either
