Feature request. Register shifts based for different days.

[saulblancoc]

Hello,

Thank you so much for your work here, it is greatly appreciated.

Tho I find it lacks a little feature to be perfect. I would love for it to be able to take a --days argument. That would allow to register different shifts on specific days, in my case that would be Fridays.

E.g. instead of running factorialsucks -email ****@***.** -y 2024 -m 5 --ci 08:00 --co 17:30 and then needing to edit Fridays manually, I would run this two different commands:

factorialsucks -email ****@***.** -y 2024 -m 5 -d 1,2,3,4 --ci 08:00 --co 17:30
factorialsucks -email ****@***.** -y 2024 -m 5 -d 5 --ci 08:00 --co 15:00

Hope that is comprehensible. If it isnt too much work, I think it would be worthy. Thank you!
