set-exif timeout with mass edit of multi-gb files

[deanjarnold]

Describe the bug

When mass editing EXIF information for large multi-gb files the process times out, the EXIF values are not updated and temporary files (suffix exiftool_tmp) remain in the folder.

Steps To Reproduce

1. Have multiple (10+) large Multi GB (2Gb+) MOV files in a folder within NextCloud/Memories Folder view.
2. Select all of the files.
3. From ... select "Edit metadata".
4. Change a value e.g. year
5. Select Save
6. Process bar will move.
7. Timeout notifications will appear in top right of nextcloud/memories UI.
8. Process completes, but some files exif information is unchanged.
9. Files with an extension suffix of "exiftool_tmp" will exist in the folder the files are located.
10. Logs will containe timout errors.

Appears EXIFTOOL_TIMEOUT timeout is 30sec (30000ms) defined a s constant in Exif.php.

To work around I changed the EXIFTOOL_TIMEOUT to 120sec (120000ms) and the timeout no longer occurs.

The issues appears to a combination of the file size and the number of concurrent and enqueued set-exif processes launched by the mass edit.
