Nicolas Mowen 03c8e5ce8d Improve face recognition (#15205)
* Validate faces using cosine distance and SVC

* Formatting

* Use opencv instead of face embedding

* Update docs for training data

* Adjust to score system

* Set bounds

* remove face embeddings

* Update writing images

* Add face library page

* Add ability to select file

* Install opencv deps

* Cleanup

* Use different deps

* Move deps

* Cleanup

* Only show face library for desktop

* Implement deleting

* Add ability to upload image

* Add support for uploading images
