Add user-specific / folder specific filter criteria

[copperheadclgp]

Use case for this enhancement request

1. Nextcloud server is configured to allow multiple users to upload photographs to shared folders owned by devices (a digital picture frames connected by davfs)

2. Users will be uploading from smartphones with variable image sizes between 4-8 MB. To address download sizes, a jpegoptim script is being run to reduce the image quality. This script is as follows:

#/bin/bash
/usr/bin/jpegoptim -m90 /mnt/nextclouddata/"$1"
/usr/bin/php /var/www/nextcloud/occ files:scan --path="$1"

The script is being called by the following command inside of the flow:

/home/myuser/jpegoptim.sh %n

Expected behaviour

The jpegoptim script should be triggered only when jpeg files are being uploaded to a specific account / directory within Nextcloud. Here is an example regex expression that reflects the desired level of granularity:

/^\/mnt\/nextclouddata\/userA\/files\/"Picture Frame"\/.+(\.jpg|\.jpeg)$/

Actual behaviour

The "File name" criteria is limited to the file name itself, and is thus global within the Nextgen server. For this use case, that means that any jpeg / jpg files uploaded to the server will be compressed, regardless of location or need.
