Update libcurl

This updates to the latest libcurl.

Changes in curl:
* 0.4.42: https://github.com/alexcrichton/curl-rust/releases/tag/0.4.42
* 0.4.43: https://github.com/alexcrichton/curl-rust/releases/tag/0.4.43

Changes in libcurl:
* From 7.80.0 to 7.83.1: https://curl.se/changes.html

There were several security issues addressed recently (https://curl.se/docs/security.html), however, I don't think any of them are particularly concerning for us.
