Enhance Any Cloud to work with BulkImport module

[jonasrosland]

Describe the bug
Thumbnails aren't created when uploading image files to a new item. File are stored in Wasabi. When trying to recreate them using EasyAdmin, it complains that the files do not exist. Do I need to do anything specific for S3 and thumbnails?

To Reproduce

1. Upload image file
2. Original file is stored correctly
3. Derivative files aren't created

Expected behavior
Thumbnails should be created

Screenshots
EasyAdmin skips all files, as it cannot find them:

This is the result of uploading images. The originals are still available though.

Versions
Omeka S 4.0.4
AnyCloud 3.0.1
EasyAdmin 3.4.14

Additional context

One more screenshot to show the error messages from EasyAdmin

And here's a new upload. I'm starting to wonder if it's the other modules messing with things here.

[jonasrosland]

Sorry for the flood of screenshots here, but it seems like the BulkImport module does conflict with this module, as disabling it gives me the correct result.

For these modules to not conflict, this would need to be a new feature. I've tagged this as an enhancement request and with help wanted. Pull requests to allow these modules to work together are welcome.
