More expire time options

Description

Thanks for all the years of pasteall!
I think, for sharing with people online, more short-term expire options should be available, like definitely "one day" is good for some sharing in chats.
I'd have: 1h, 2h, 12h, 1 day, and then the rest...

Acceptance Criteria

There is already 1h and 1day on dpaste.de. I dont think 2h or 12h add much benefit there.

You can customize this in your own dpaste installation. https://dpaste.readthedocs.io/en/latest/settings.html
