[lh0x00]

Pull Request Description

Summary

This PR enhances _CustomMarkdownify with two features:

1. Automatic Code Language Detection:

   • Uses guesslang to detect programming languages in code snippets.
   • Provides a fallback if guesslang is not installed.

2. Inline Images in Table Elements:

   • Keeps inline images within td, tr, div, p, and span elements.

Changes

• Imported Guess from guesslang with a fallback.
• Added code_language_callback to detect code languages.
• Updated options to include keep_inline_images_in.

How to Test

1. Install guesslang via pip install guesslang.
2. Convert a document with code snippets and images in table elements.
3. Verify correct language detection and image retention.

@gagb @afourney I find it useful when working with LLM applications (assistants, research, etc.), so I recommend it. What do you think?
