FEAT: Include filename for each function in Markdown

[runmaxde]

In cases where functions have the same name but exist in separate files, it becomes difficult to distinguish between them solely based on the function name. It would be beneficial to have a flag that includes the filename for each function in the generated documentation.

Expected Behavior

The addition of a flag in JSDoc-MD that includes the filename alongside each function would enhance the readability and clarity of the generated documentation. This feature would be particularly useful in cases where functions have the same name but exist in different files, ensuring that each function is uniquely identifiable.

Thanks and best regards👋
