Feature: Allow Deferred Responses in iqCallee

[adamskki]

In my project, I have a requirement to return a response from an IQ query in a separate process after some time (depending on the processing time).

The current implementation of the iqHandler function expects an immediate response from the handler. If no response is returned, an error ("service-unavailable") is returned. However, in my case, I cannot return the response immediately because it will be sent by a separate processing task after some delay.

What do you think about adding an optional new parameter (flag) to the iqCallee function, such as deferReply? By default, this parameter would maintain the current behavior, but when set to true (for example, deferReply: true), it would allow the function to return without waiting for the response.

I can prepare a proposal for such a change, but first I'm curious to hear your opinion
