fix: added custom token pricing

[sauravpanda]

PR Description

This pull request aims to address the issue of custom token pricing by introducing changes to the configuration and provider files.

Changes Made

• In the config.json file, the language model's model attribute has been replaced with a nested object containing name, input_token_cost, and output_token_cost properties.
• In the provider.py file, default input and output token costs have been added to the LLMProvider class, and the chat_completion method has been updated to utilize the new token cost values.

These modifications enable the customization of token pricing for the language model, providing more flexibility and control over the cost associated with input and output tokens.
