calibre 9.16.0

Version 9.16.0

New features:

• Read aloud: Add the high quality Kokoro voices, which sound much more natural than the Piper voices, especially for English
• To use them, select the Piper backend in the Read aloud configuration and choose one of the Kokoro voices. The voice will be automatically downloaded the first time it is used.
• News download: Support for downloading news from websites that block automated access by using the camoufox browser
• Some news sites, such as The New York Times, The Economist and The Atlantic, block all lighter weight ways of fetching their pages. Recipes for these sites now use the camoufox browser, which is automatically downloaded the first time such a recipe is run. Recipe authors can use it by setting browser_type = 'camoufox' in their recipes.
