I added a "/retry" command to retry for getting another answer. (#188)

* I added a "/retry" command to retry for getting another answer.

- Implemented to pop messages until hitting the last user message. Then
  extracting the users last message and sending it again. This will also
  work with state files and after manually popping messages.
- Updated the README to include /retry
- Update the README for "pop" with parameter and changed default to 3 as
  this will pop "function/assistant/user" which is the usual turn
  around.

* disclaimer
