Feature request: Excluded tag filters

[Ziron]

Would it be possible to add an inverted tag selection to exclude certain tags from the list, instead of only specifying tags to show?

Like for example:

filters:
  tag: !ignoredTag 

or

filters:
  excludedTag: ignoredTag 

I think it would be very helpful!

After looking at the source code I found the undocumented filter "excludeNoteId" which also is a great feature and solves my problem for now!
But it would be nice to be able to exclude notes more generally by tag.
