Connect to ContentSniffed signal.

This signal is emitted after signalMessage::got-headers.

If content sniffing is disabled, or no content sniffing will be performed, due to the sniffer deciding to trust the Content-Type sent by the server, this signal is emitted immediately after signalMessage::got-headers, and type is null.

Parameters

`callback`	signal callback delegate or function to connect `void callback(string type, string[string] params, soup.message.Message message)` `type` the content type that we got from sniffing (optional) `params` a #GHashTable with the parameters (optional) `message` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
