希望增加 HTTPS 代理 的支持

[yeahwong]

surge、sing-box、mihomo 都支持 https 代理，但目前 sublink-worker 还不支持。请求加入 https 代理格式。

谢谢。

mihomo http

proxies:
- name: "http"
  type: http
  server: server
  port: 443
  # username: username
  # password: password
  # tls: true # https
  # skip-cert-verify: true
  # sni: custom.com
  # fingerprint: xxxx # 同 experimental.fingerprints 使用 sha256 指纹,配置协议独立的指纹,将忽略 experimental.fingerprints
  # ip-version: dual
  headers:

surge http

[Proxy]
ProxyHTTP = http, 1.2.3.4, 443, username, password
ProxyHTTPS = https, 1.2.3.4, 443, username, password

sing-box
