incorporate GDPR-dump as an alternate for anonymised backups

[IanFiretoys]

Hi, more of a feature request than a bug, but it would massively streamline operations if you could incorporate the drop-in replacement for mysqldump, GDPR-dump that can be called by an --anonymous flag in the command:

https://github.com/machbarmacher/gdpr-dump

example usage: ./mage2-backup.sh --backup-code --skip-media --anonymous --src-dir=/path/to/magento2/root --dest-dir=/path/to/destination

the drop in version of gdpr-dump needs parameters added to a [mysqldump] section in the user's my.cnf file but would certainly smooth things in terms of dev environments considerably.

(there is a non-drop in version by https://github.com/Smile-SA/gdpr-dump that has more configurable options through a .yaml but i imagine that would be more hassle to incorporate, it is however more actively developed)
