+- [#85](https://github.com/babashka/http-client/issues/85): add SOCKS5 proxy support with `:proxy {:type :socks5 :host <string> :port <long>}`, and optional `:user` and `:pass`. `java.net.http` connects through HTTP proxies only, so this starts an HTTP proxy on 127.0.0.1 that tunnels over the SOCKS5 proxy. You can use a SOCKS5 proxy only in the `:proxy` map of `client`. CI tests it against microsocks only.
