facerecognition: change to FACE_MODEL=3 and adjust memory values

@matiasdelellis can we also lower the limit in

all-in-one/community-containers/facerecognition/facerecognition.json

Line 16 in b1d2496

"nextcloud_memory_limit=4096M"

and

all-in-one/community-containers/facerecognition/facerecognition.json

Line 24 in b1d2496

"php /var/www/html/occ face:setup -M 4G",

then?

Or does it need to stay as high due to

all-in-one/community-containers/facerecognition/facerecognition.json

Line 25 in b1d2496

"php /var/www/html/occ config:app:set facerecognition analysis_image_area --value 4320000",

?

"nextcloud_memory_limit=4096M"

The absolute minimum is 512 MB that you have to set to allow it to work. but if the user has a lot of images (50 thousand?) they will probably need more memory to perform the face clustering step, therefore we must leave a reasonable value to start.

I will try to evaluate but maybe 2GB could be something very reasonable value.

"php /var/www/html/occ face:setup -M 4G",

1G, it is a mere formality but we must assign it.

"php /var/www/html/occ config:app:set facerecognition analysis_image_area --value 4320000",

It's a lot, but it will work without problems.

p.s: You can also increase the memory only for the commands and leave the default configuration.

php -d memory_limit=2048M

all right, adjusted :)
