  51.  * @typedef {Object} Websites[]

  65.  * @description An array of website configurations for extracting episode links.
  66.  *
  67.  * @note To add a new website, follow these steps:
  68.  * 1. Create a new object with the following properties:
  69.  *    - `name`: The name of the website.
  70.  *    - `url`: An array of URL patterns that identify the website.
  71.  *    - `thumbnail`: A CSS selector to identify the episode thumbnail on the website.
  72.  *    - `addStartButton`: A function to add the "Generate Download Links" button to the website.
  73.  *    - `extractEpisodes`: An async generator function to extract episode information from the website.
  74.  * 2. Optionally, add the following properties if needed (they arent used by the script, but they will come in handy when the animesite changes its layout):
  75.  *    - `animeTitle`: A CSS selector to identify the anime title on the website.
  76.  *    - `epLinks`: A CSS selector to identify the episode links on the website.
  77.  *    - `epTitle`: A CSS selector to identify the episode title on the website.
  78.  *    - `linkElems`: A CSS selector to identify the download link elements on the website.
  79.  *    - `epNum`: A CSS selector to identify the episode number on the website.
  80.  *    - `_getVideoLinks`: A function to extract video links from the website.
  81.  *    - `styles`: Custom CSS styles to be applied to the website.
  82.  * 3. Implement the `addStartButton` function to add the "Generate Download Links" button to the website.
  83.  *    - This function should create a element and append it to the appropriate location on the website.
  84.  *    - The button should have an ID of "AniLINK_startBtn".
  85.  * 4. Implement the `extractEpisodes` function to extract episode information from the website.
  86.  *    - This function should be an async generator function that yields Episode objects (To ensure fast processing, using chunks is recommended).
  87.  *    - Use the `fetchPage` function to fetch the HTML content of each episode page.
  88.  *    - Parse the HTML content to extract the episode title, number, links, and thumbnail.
  89.  *    - Create an `Episode` object for each episode and yield it using the `yieldEpisodesFromPromises` function.
  90.  * 5. Optionally, implement the `_getVideoLinks` function to extract video links from the website.
  91.  *    - This function should return a promise that resolves to an object containing video links.
  92.  *    - Use this function if the video links require additional processing or API calls.
  93.  *    - Tip: use GM_xmlhttpRequest to make cross-origin requests if needed (I've used proxy.sh so far which I plan to change in the future since GM_XHR seems more reliable).
