Backwards incompatible changes

• [Macro] Macro.unpipe/1 now returns tuples and Macro.pipe/2 was removed in favor of Macro.pipe/3 which explicitly expects the second element of the tuple returned by the new Macro.unpipe/1
• [Path] The functions in Path now only emit strings as result, regardless if the input was a char list or a string
• [Path] Atoms are no longer supported in Path functions
• [Regex] Regexes are no longer unicode by default. Instead, they must be explicitly marked with the u option
