Crash when using aom, speed=4, on macos

[jnoring-pw]

macOS 14.4.1 (23E224), Apple M3 Max, python 3.12, pillow-avif-plugin 1.4.4 (cannot reproduce with 1.4.3)

When running the following code, I hit some sort of exception down in native land:

import pillow_avif
from PIL import Image
image = Image.open("/Users/jnoring/Downloads/blah.png")

# This is fine
image.save("/Users/jnoring/Downloads/blah.avif", codec="aom")

# Boom
image.save("/Users/jnoring/Downloads/blah.avif", codec="aom", speed=4)

Here's the dump file:
crash.txt

And the offending thread:

One other detail: this definitely is a macOS thing. I have no reproduction on x86/arm linux.

Thanks @fdintino !

[fdintino]

Once the build finishes in CI I'll be uploading the 1.4.6 release to PyPI with this fix. When you have a chance could you confirm that it does in fact fix the issue? Thanks.

[fdintino]

okay, I've uploaded the release.

[jnoring-pw]

And, confirmed: no crash, and all my tests pass. Thanks so much, @fdintino
