Extract params from the URL fragment part (after '#') of a vector.im universal link.
Extract params from the URL fragment part (after '#') of a vector.im Universal link:
The fragment can contain a '?'. So there are two kinds of parameters: path params and query params.
It is in the form of /[pathParam1]/[pathParam2]?[queryParam1Key]=[queryParam1Value]&[queryParam2Key]=[queryParam2Value]
