## Added

- Added function for dealing with query strings as maps: `query-string->map`,
  `map->query-string`, `query-map`, `query-encode`, `assoc-query`,
  `assoc-query*`.

## Fixed

- Fix query string normalization, for delimiter characters like `=` and `+`
  there is a semantic difference between the encoded and decoded form, when they
  are encoded in the input normalization should not decode them and vice versa
