Support Files as Input for Messages Exceeding Character Limit

[Muchaszewski]

Description:
I would like to have support for uploading files as input for messages that are too long to fit within the standard character limit of a single Slack message. This will allow users to provide more context and information when interacting with the GPT model, leading to better and more accurate responses.

Background:
The current implementation of the Slack GPT Bot can only see messages in text, however, when users need to send a message to the bot that exceeds the character limit, they must split the message into multiple parts, which can be cumbersome and may affect the quality of the generated responses. AI might fail to understand that there will be more parts to the message.

Proposed Solution:

1. Implement a feature that allows users to upload a file (e.g., .txt, .docx, or .pdf) containing their input message when it exceeds the character limit.
2. The bot should parse the file and extract the text content, ensuring compatibility with various file formats.
3. The extracted text should then be passed to the GPT model for processing and generating a response.
4. Consider implementing a character limit for the file content to prevent excessively large inputs that could negatively impact the performance of the bot and the GPT model.

Acceptance Criteria:

• Users can upload a file containing their input message when it exceeds the character limit in a single Slack message.
• The bot is able to parse the file and extract the text content, supporting a variety of file formats.
• The GPT model generates a response based on the extracted text from the file.
• A reasonable character limit is set for the file content to maintain optimal performance.

Additional Notes:

• This feature should be thoroughly tested with various file formats and sizes to ensure compatibility and maintain performance standards.
• Documentation should be updated to include information about the new feature and its usage.
