Make the date library support modular - Add support for Jiff

[Permik]

Hello

This looks like an awesome library that I'll definitely be using in the future!
For now it seems that the date parsing and data types are from Chrono, but for my future projects I'll be definitely moving to use the Jiff library by BurntSushi.

Is there any plans to make the date library/data types configurable depending on what time library the user prefers?
(I'll try to contribute the feature when/if I get to it, unless someone nerdsnipes the feature first.)

Also, if you want to split this issue to two different issues, please go ahead!

Cheers!

Hiho, thanks for the interest. I've heard of jiff before but haven't looked at it closely. I haven't looked at jiff much before but it seems to have a nice api to construct dates. icalendar has it's own CalendarDateTime wrapper but uses chrono internally, but maybe it might be possible to provide From implementations for jiff types. Maybe that could even make some of the examples nicer, which are currently using slightly deprecated chrono APIs.

If you want to give it a try be my guest.
