add extended support, supports uuid and naivedatetime

This is behind a feature crate, not sure how well is this implemented since I've never actually developed crates, please merge if you find this useful, you can also get the code form my fork, modify whatever you want and commit from your account, I just want the features, thanks

Note about adding chrono as (optional) dependency:
This would introduce a CVE and it is unclear if/when this will be resolved for chrono.

Instead, time, which is used by chrono itself, could be used directly as an alternative.

I'm pretty sure we don't call the code that is vulnerable here in any way, I agree with your concerns however other crates I use in my projects depend on chrono so I don't plan to change this, if you want you could change it, or suggest how to fix it, thank you!

@mvntainer Could you instead use the Display functionality instead?
