New "Interleave" option in image format settings, enabled by default in old files and disabled by default in new files to write multi-part files. By not storing all channels interleaved, it is possible for other applications to load individual passes more efficiently. This might also work better with compression. We follow the OpenEXR docs in that the channel name is the full Layer.Pass.Channel rather than just Channel. Some other renderers (e.g. Houdini Karma) write just the channel and that is what our reading code assumed so far. I've verified that Nuke can read the multipart EXR files produced by Blender, including multiview and cryptomatte. Fix #123727 Pull Request: https://projects.blender.org/blender/blender/pulls/146650
