Allow option to transform tags about yarle

Breaking news: Obsidian 0.10.3 supports nested tags!
You can now nest tags with unlimited hierarchies using the syntax #parent/child/subchild.

Soo, I think we coud go for it. About providing a function: I'm not sure that an average user of EN could provide a replace function, but i think setting the character used to separate nested tags in EN, and an other one to what it should be replaced is much kore understandable for the common.

@finn-matti Wouldn't be enough if we just make the separator of the nested tags configurable? Like this:
config.json:

{
  nestedTags: {
          separatorInEN: '.',
          separatorToBeApplied: '/'
}
}

I was thinking that maybe some people would use a transform function on their tags in completely different ways than I have in mind. I am also fairly sure that this separation is not very common. I think people are more likely to have native nested tags in Evernote.

Indeed I use tags like:

• recipe-type
  • side-dish
  • main-course
  • desert
• recipe-source
  • book1
  • book2
  • book3
• recipe-duration
  • 15min
  • 30min
  • 60min

And I wouldn't like to keep this hierarchy in Obsidian. Something like #recipe-type/side-dish.

Also, like already mentioned in #19, I would like to have my tags in frontmatter without the # currently hard coded. But probably solving this issue will automatically solve #19.

Thanks!
