support extended cron syntax

Does this package have any plan to support non-standard cron syntax? Like, https://en.wikipedia.org/wiki/Cron#Non-standard_characters

I am using this package really well but I needed to use extended syntax for some reasons. Now I extended the codes myself but it would be great if these syntaxes are supported natively.
