Integrate english-to-cron crate

[kaplanelad]

It would be beneficial to integrate the english-to-cron crate into your library to allow users to generate cron expressions using plain English text.
This would enhance the usability of your library by making it easier for developers who are less familiar with cron syntax to define scheduling rules.

if this is something that you want, I'd love to open a PR for that

Hi, thanks for the suggestion! I think I'd prefer to keep this crate focused on plain cron expressions. The glue code needed to go from sentence to cron expr to Schedule seems pretty minimal, and I'd rather not take on the dependency.
