Allow blacklisting/whitelisting tags

Describe the feature you'd like to request

I run a bakery, so I have thousands of photos of food/bakery/staff at work and so on. Smart tagging is immensely helpful here.

However, not all tags are useful, even if they were correct...

Describe the solution you'd like

I would never need a tag of snails, or many other things which I can see my photos have been tagged with, for example:

• bear
• beetle
• bird
• boat

etc. Even if there does happen to be a photograph of a bear, I don't need to know about it.
Looking through the tags that have been auto-assigned, I am only interested in a few, such as: food, kitchen, outdoor, indoor, bread.

I would love to be able to either whitelist or blacklist tags. Perhaps blacklisting would be more useful, I could spend thirty minutes going through the tags that have been created and blacklisting one that I don't like.

Describe alternatives you've considered

I can't think of any alternatives, at the moment it seems to be all tags or no tags.

The issue names no files, tests, or entry points. Start by reviewing the repository architecture and existing smart-tagging behavior, then clarify whether filtering applies during tag generation, storage, or display; done requires an agreed whitelist/blacklist scope and acceptance tests.
