Further comments

This is an experimental change and may lead to more maintenance overhead than desired. Anyway, I wanted to try it out and gather some feedback.

It builds successfully on linux/amd64 and linux/arm64 It also builds on darwin/amd64 with warnings.

It is able to read images 1-3 from https://github.com/tigranbs/test-heic-images but it segfaults for image 4.

Now the following questions arise:

1. Is it a generally embraced addition?
2. Is it possible to catch the SIGSEGV?
3. Should target architectures be conditionally included?

+1 on this feature, please merge.

This feature adds a dependency on CGO. With that our existing release pipeline will be broken. It cannot be merged without rewriting the build pipeline to support CGO cross-compilation.
