This library tries to (rightly!) match the formant from [the spec draft](https://github.com/lightning/blips/pull/26#discussion_r1605598764) `402 macaroon="{macaroon}", invoice="{invoice}"` However, I think this is a typo in the draft we should go with the version without the `"` surrounding the string values. Your input is very much welcomed in the spec discussion :+1:
