[feature request] delete a tag in all notes

[pcause]

this is a great and useful library. one issue that obsidian doesn't solve is that I can't delete a tag in all notes, whether front matter or inline in the note. this would be a useful addition. if you add please handle the case where the tag has subtags #xxx/yyy and either delete #xxx/* or allow the subtag to be promoted to a tag (#xxx/yyy => #yyy)
