add Requests logger

[panz3r]

This PR adds a Requests logger handler to the main http.Handler that can be enabled using a new logger option.

The logger handler implementation is based upon rs/zerolog logging library and supports printing log events as either JSON or pretty text (enabled via another option: log-pretty).

Example JSON log output

{
  "level": "info",
  "method": "GET",
  "path": "/",
  "code": 200,
  "size": 449,
  "duration": 4.654542,
  "ipAddress": "127.0.0.1",
  "userAgent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0",
  "referer": "",
  "time": "2023-07-06T12:34:56+00:00"
}
