.nomedia seems to be ignored

[Ellpeck]

Describe the bug
In previous versions of Recognize, any files and directories whose parent directories contain a .nomedia or .noimage file weren't processed by Recognize. However, ever since version 3 of Recognize, this feature seems to be missing.

I briefly checked the repository and it seems that the only file that was referencing .nomedia and .noimage don't exist anymore in the current versions, though I don't understand the codebase well enough to know if this actually means that they're not being queried anymore.

Note: This issue was already briefly mentioned in #337, but that issue is mainly about a feature request so I thought it would make the most sense to open a proper report for this issue.

To Reproduce
Steps to reproduce the behavior:

1. Add a .nomedia file to a directory containing images, or which has a subdirectory containing images
2. Install Recognize

Expected behavior
The directory containing the .nomedia file is ignored for recognition, including all of the images in it and all of the images in all of its subdirectories.

Recognize (please complete the following information):

• JS-only mode: No
• Enabled modes: Object detection, though this also seems to occur with the other modes

Server (please complete the following information):

• Nextcloud: 25.0.0 RC5
• OS: Ubuntu Server 18.04
• RAM: 12GB
• Processor Architecture: x86

I can confirm this behavior.
I have faces recognized from e.g. album covers, which are excluded from my Photos with .noimage and .nomedia.
But when I click on a face, I see no pictures - obviously because they are excluded.
Same server setup as you, only OS is Ubuntu 20.04

Also getting the same behavior, also on album art. It would nice to configure directories to scan or avoid.
