Outlook msg format support

Can we have Outlook msg file support as well please.

There is no library for it currently and this has a lot of use cases for organisation and individuals using outlook.

A bit supplement request on this topic:

1. msg format is not supported in the new Outlook layout
2. The new Outlook can only export (print) to PDF format. However, it cannot be extracted by markitdown, given that other PDFs conversion works well and PDF is supported in this library.

MSG is still supported—just select a few messages and drag and drop them outside into a folder. It is very useful, and Microsoft should never discontinue this. This is especially beneficial for longer projects where many people work at different times over a few months to a year, allowing them to access earlier communications from MSG files saved in respective folders. I have seen many organizations using this, and I personally use it a lot as well.

PDFs are handled one by one, and that still results in some functionality loss. Since "Markitdown" is from Microsoft itself and MSG files internally have an HTML-based backend for formatting, it would be nice to have such functionality. This would allow users to import them into a database or directly run formatting processes, which would provide better support for AI models.
