Import already tagged faces with 3rd party software

[ippocratis]

Describe the enhancement you'd like
An option to add people faces already tagged with another software.Popular options are Google photos and photoprism

Describe why this will benefit the LibrePhotos
Resource economy:i'm running librephotos on a low power raspberry pi 400 and face classification is resource intensive
Time econony:face clustering/grouping is mostly inaccurate (in my experience) with librephotos and I have to manually tag almost each face .it will save me huge amount of time to add already tagged faces

Additional context
Thanks and keep up

A great example is using the industry standard for face tagging and this plugin make possible to collect this information.
