0.11.2

• Adds the ability to write #[logos(subpattern name = r"regex")] on the token enum, which is then used as a "subroutine" in regex rule definitions with the syntax (?&name) (by @CAD97, #131). Example:

  #[derive(Logos)]
  #[logos(subpattern xdigit = r"[0-9a-fA-F]")]
  enum Token {
      #[regex("0[xX](?&xdigit)+")]
      LiteralHex,
  
      // ...
  }
