[Bug] Opening ZIP OME-Zarr does not work with all browsers

[tischi]

Describe the bug

Opening a zipped OME-Zarr results in a browser error.

To Reproduce
Steps to reproduce the behavior:

1. Use Chrome on a Mac (see below)
2. https://biongff.github.io/vizarr/dev/?source=https://static.webknossos.org/misc/6001240.ozx
3. See error: Error: server replied with "Failed to fetch" when loading the resource

Environment

• Mac OS 13.7.5; Apple M2
• Browser: Chrome

This seems to be a CORs/HTTP issue related to the resource rather than an issue with zipped ome-zarrs, e.g. you cannot open it in the ome-ngff validator either due to the same issue. @tischi Were you able to load it in other browsers?

[AlexSurtees]

I managed to serve the file locally and can confirm that there is an additional issue even once the CORs issue is resolved.

@AlexSurtees to download above dataset, and serve locally. Confirm working, and share screenshot here.

Downloaded dataset, same error as #89 which is fixed in #95. Image loads but channel metadata is missing, this is handled gracefully with a warning. Missing channel metadata causes the contrast limits not to be set, so it displays strangely. I believe this is an issue with how the .ozx file was produced, rather than with the viewer, as I could not find the channel metadata.
