New method openIn

[thomasv]

Great project!
I would appreciate methods openIn() and openAt() which could be the counterparts to closeIn() and closeAt().
What do you think?

I think this would comes handy, working on it :). Thank you for your time filling an issue.

Sorry Franck, got completely absorbed on another side project. Will give it a try this weekend thanks for your patience 🙏

After a quick dig into the code, I might need to take a little bit more time to make a refactor:

1. Currently the openings is a list of days related to hour spans -> I think this is wrong, if you want to have exceptional openings, this is limiting
2. Closing is a list of time spans -> This is the reverse issue of 1., I should make sure both openings and closings actually supports time spans and day/hour spans
3. The code is outdated (by basically 2-3 years) -> I would like to bring support for newest Node.Js versions (currently the package only support Node <= 14, newest is 19)
4. Once I did this, I will be able to refactor the code to avoid working with hand-made date manipulation functions but using a state-of-the-art Date manipulation, I am used to use Carbon for PHP which lifts a lot of burden regarding this kind of task looking for something similar in JS to be able to work with Intervals etc...)

Hope it sounds ok and you're not in a hurry, sorry for the inconvenience!
