Add API documentation and underground station importer
- Introduced a new HTML documentation page for the oradio API, including a JavaScript file to handle dynamic content and API requests. - Added a CSS file for styling the documentation page. - Implemented an underground station importer script that fetches data from Radio-Browser and writes it to a JSON file. - Created a stats module to compute and manage vote and play statistics for radio stations. - Added a polyfill for modulepreload to ensure compatibility with older browsers.
