sterni a5f2b446aa feat(sterni/nix/url): implement urldecoding
We use builtins.split directly as it should be a bit more efficient as
lib.splitStrings. Also its returning of a list for every regex match is
useful to update the state while parsing the tokens:

* The tokens are obtained by splitting the string at every '%'
* Everytime we see a boundary (that is a list in the returned
  list of builtins.split), we know that the first two chars of
  the next string are a percent encoded character.

One implementation flaw is that it will currently crash if it encounters
mal-formed URLs (since int.fromHex chrashes if it encounters any non
hex digit characters) and accepts some malformed urlencoding like
"foo %A".
