Allow for easier function configuration for custom endpoints.

• Added tool_format to the db, this is a boolean that changes whether or not functions are sent to the endpoint via tools or functions. True means it sends as tools, false means it sends as functions.
• calls.py was only sending functions if the model was an official OAI model. I added a few checks and dropped the function check code out of the OAI model check as to hopefully not break compatibility.
• I tested with functions on and off, tool_format on and off, made sure ::assist had no embedding errors, and made sure that function_calling still worked of course. I do not have access to an OAI endpoint so I'm not able to test that directly, but I do not believe that any changes made are breaking.
• I tested changes using Ollama and LM Studio and was able to get function calling working very quickly and painlessly.

Accidentally pushed this to the wrong repo.

I will submit this again after testing.

Made some more changes and tested everything. All seems to be in working order so I went and re-opened the PR.

There have been multiple changes since this PR was made, please resolve any conflicts. Additionally the minor version number will need to be bumped for this pr since it is adding a new command

Before accessing properties on 'db', such as 'db.endpoint_override' and 'db.tool_format', consider adding a guard to ensure 'db' is not None to prevent potential attribute errors.
