Update chrono-tz and some other packages and some cleanup

[omid]

fixes #88

[fmeringdal]

Thanks @omid ! Will review these changes next week

[fmeringdal]

Thanks again, left some comments. Regarding unwrap -> expect for non-test code, it might be worth to try adding this to the crate root if it doesn't add to many complaints

#![cfg_attr(not(test), deny(clippy::unwrap_used))] // Not sure if syntax is correct tho!

@omid Looks good to merge now. I know the commit history in this repo is terrible, but let us try to improve it moving forward. Could you please squash the commits and we can merge + release? Thanks!

[omid]

@fmeringdal we can use the squash and merge feature of GitHub 👍

[fmeringdal]

True, but I don't think the squashed commit message would be particularly nice. Something like this would be great:

"Prepare 0.11 release by updating chrono-tz
Additionally, this commit includes:

• Bumping MSRV to v1.64.0
• Temporarily allows clippy warnings in CI
• General cleanup work"

Wdyt?

[omid]

You can set the commit message in GitHub also. Like what I just did 🙈
