Create Autogen agent (copy of microchain) with additional Reasoning agent

[gabrielfior]

Investigate Autogen as a replacement for microchain, allowing for

• Similar easy-to-implement function registration framework
• Additional agent (Reasoning Agent - link) that assesses the previous output of the agent and gives an assessment of that - might be useful for assessing the bets it placed

Leaving this as ToDo for now - microchain is still good enough for the time being, no need to migrate now cc @evangriffiths
