Things to discuss with @pokey

• Are hats only ever one character? Currently we export a start/and range because it the decoration range

[pokey]

Today they're only one character, but it's possible they could be more than one in the future, eg cursorless-dev/cursorless#71 (and potentially cursorless-dev/cursorless#276)

I wouldn't go crazy trying to support more than one character, but if it doesn't make life harder I'd be inclined to support ranges

[phillco]

OK. @rntz was a little confused about the API in the JSON that we were writing, since they were expressed as ranges but were only ever one character long. Guess we'll leave them as ranges for now!

[pokey]

Yeah that's fair. If you think it will be simpler / less confusing to assume they're one char, that's prob fine
