wp_privacy_delete_old_export_files()

Cleans up export files older than three days old.

Description

The export files are stored in wp-content/uploads, and are therefore publicly accessible. A CSPRN is appended to the filename to mitigate the risk of an unauthorized person downloading the file, but it is still possible. Deleting the file after the data subject has had a chance to delete it adds an additional layer of protection.
