[Feature] Draw and Redact in image editor

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

The feature

With Google Photos recently rolling out their new Redact tool as part of the Markup section - allowing users to blur or pixelate sensitive areas of photos and drawing. It would be great to see something similar in Immich's image editor. This would be especially useful before sharing photos externally, without having to export and edit them in a third-party tool first.
