* initial framework

* initial conv

* fix module error

* feat: Add 3 new features to Moderator (sotopia-lab#266)

* feat:introduce booting procedure, saving, and ending chat to moderator

* fix: moderator will now ignore none AgentAction, Observations now don't have to include all channels in the mapping

* merge changes of example into the original one

* fix: 1. save() method now accepts push_to_db config 2. booting()'s waiting time is changed to 0.1 sec

* fix: rewrite booting() so that different agent will receive different background information

* fix: moderator now inherits from Node directly, instead of from BaseAgent
