Convert HWPX (Hanword) to MD GFM

HWPX (Hangul Word Processor XML) is an advanced document format used by Hanword, developed by Hancom. It serves as an XML-based alternative to the proprietary HWP format, enhancing interoperability and accessibility. Introduced to improve document structure and compatibility, HWPX enables easier data exchange, integration with various applications, and better support for modern document processing workflows. It is widely used in South Korea for official documents, offering structured content representation while maintaining the rich formatting capabilities of Hanword.

Markdown (MD) is a lightweight markup language with a file extension MD, commonly used for formatting readme files, documentation, and comments in GitHub repositories. GitHub-Flavored Markdown (GFM) extends the original Markdown's capabilities, adding features like tables, task lists, and auto-linking URLs. Markdown's simplicity and effectiveness in creating formatted text using a plain text editor made it widely adopted in the developer community. GFM, in particular, is optimized for use on GitHub, enhancing collaboration and code documentation.
