Bump chrono from 0.4.21 to 0.4.23

[dependabot]

Bumps chrono from 0.4.21 to 0.4.23.

Release notes

Sourced from chrono's releases.

0.4.23 is the next 0.4 release of the popular chrono date and time library for Rust. After the 0.4.20-0.4.22 series that brought chrono back to life after a long hiatus, development has been fairly quiet, allowing us to start planning changes for the 0.5.0 release. As such, we've started deprecating some APIs that are likely to be removed in 0.5. If you have any feedback on these changes, please let us know in the issue tracker!

Deprecations

• Deprecate methods that have an _opt() alternative (#827)
• Deprecate usage of the Date<Tz> type (#851)

Features

• Optimize RFC 3339 (and RFC 2822) encoding (#844, thanks to @​conradludgate)
• Addition and subtraction with the Days type (#784)
• Add NaiveDateTime::from_timestamp_millis(_opt) (#818, thanks to @​Pscheidl -- backported in #823)
• Allow for changing TZ variable and cache it for Local timezone (#853)
• Add optional support for the arbitrary::Arbitrary trait (#849, thanks to @​greyblake and @​asayers)

Fixes

• Support tzdb location on AIX (#826)
• Fix warnings in documentation (#847)

On behalf of @​esheppa and @​djc, thanks to all contributors!

0.4.22

Unfortunately the introduction of the iana-time-zone dependency in 0.4.21 caused some new regressions with lesser known platforms. This release fixes all of the issues we've encountered, improving the situation on some WebAssembly targets, SGX and on macOS/iOS. We've improved our CI setup to hopefully catch more of these issues before release in the future.

• Make wasm-bindgen optional on wasm32-unknown-unknown target (#771)
• Avoid iana-time-zone dependency on x86_64-fortanix-unknown-sgx (#767, thanks to @​trevor-crypto)
• Update iana-time-zone version to 0.1.44 to avoid cyclic dependencies (#773, thanks to @​Kijewski for the upstream PRs)
• Clarify documentation about year range in formatting/parsing (#765)
