- New feature: added `data_saver` argument in `Mangadex.extract_info()` and `Mangadex.download()` to use low quality and size image.
- Enchantment: now mangadex-downloader will always using API for fetching information and chapters for manga, **NOTE:** for grabbing manga id still need scrapping from main website.

Additional Note
- `language` argument in `Mangadex` class, `MangadexFetcher` class, and `mangadex_downloader.parser.parse_infos()` (this function is removed too) is removed, until i explore all languages code in mangadex, right now mangadex-downloader will fetch and download in English language by default.
