Jaime Marquínez Ferrándiz 67134eaba1 [YoutubeDL] rework how the format spec is processed
The spec string is processed using 'tokenize.tokenize' to split it in words and operators, the filters are still processed using regular expressions.
This should make easier to allow grouping operators with parens.
