    (send-response conn response &opt buf)
    Send an HTTP response over a connection. Will automatically use 
    chunked encoding if body is not a byte sequence. `response` should 
    be a table with the following keys:
     `:headers`  optional headers to write
     `:status`  integer status code to write
     `:body`  optional byte sequence or iterable (for chunked body) 
      for returning contents. The iterable can be lazy, i.e. for 
      streaming data.
