Add Support for Custom Prompts and Refactor Prompt Management - Reworked

[docluis]

Updated Description

• Moved formatted_dt_now (HUMAN_TEMPLATE) formatting to rewrite.py to avoid the issue of this value being assigned in prompt.py
• Added more custom prompts:
  • PLANER_SYSTEM_PROMPT_1
  • PLANER_SYSTEM_PROMPT_2
• Minor Refactor with get_custom_or_default function

Feel free to let me know if that solved the issue you mentioned :)

Previous Description

This PR introduces support for custom prompts that can overwrite predefined prompts, addressing the issue of some prompts being in Chinese only. The following updates have been made:

• Custom Prompt Support:

  • Added functionality to allow users to pass custom prompts, which can overwrite the predefined ones. This is particularly useful for choosing language and adjusting the behavior.

• New Tests:

  • Added a new test file tests/test_custom_prompts.py which demonstrates how custom prompts can be passed and tested.

• Refactoring and Consolidation of Prompts:

  • Moved some predefined prompts into a new file prompt.py for better organization and maintainability.
  • Currently, only the following prompts are supported for customization:
  • JOINER_SYSTEM_PROMPT_1
  • JOINER_SYSTEM_PROMPT_2
  • HUMAN_MESSAGE_TEMPLATE
  • JOINER_RESPONSE_HUMAN_TEMPLATE

• Open Points:

  • Only a subset of prompts is currently supported for customization, as it's unclear which additional prompts are actively used, can be removed, or will be needed in the future. Feedback on which additional prompts should be supported is welcome.

Request for Feedback:

• Suggestions for additional prompts to support or remove.
• Maybe add general overhaul of how the Prompts/Templates are defined?

Awesome project! :)
