2.9.0

Dependency cleanup release, including a few changes to examples and tests to get rid of serde_derive.

Changed

• From webpki to rustls-webpki. Thanks for the heads-up about webpki not being maintained, @RCasatta! (#98)
• Updated rustls and webpki-roots to their most recent versions.
• Maximum versions for the following dependencies to keep minreq compiling on Rust 1.48:
  • serde_json (>=1.0.0, <1.0.101)
  • log (>=0.4.0, <0.4.19)
  • chrono (dev-dependency, >=0.4.0, <0.4.24)

Fixed

• Errors when using an IP address as the host with HTTPS (tested with https://8.8.8.8). (#34)
