Registering Async Reply Enabled Async Human Input

[ShobhitVishnoi30]

The main issue that would occur without registering the async reply function is:

Async Human Input Would Not Work

Without registering ConversableAgent.a_check_termination_and_human_reply as a possible reply, the generate_reply method would never call the async reply functions like a_get_human_input. So any async human input flows would be broken - the agent would not be able to get async human input properly.

So in summary, the key problem was:

• Async human input methods like a_get_human_input would not be called
• Therefore no async human input would work
• User would not be able to provide async inputs to the agent

Registering that additional async reply handler fixed this issue and enabled the async human input flow.
