feat: autoplay for related videos
Add autoplay support for related videos. Move the playlist autoplay code into this shared script. Add the SameSite=Strict attribute to the autoplay cookie due to Firefox soon rejecting cookies which use SameSite=None without the secure attribute. Closes: #50 Signed-off-by: Jesús <heckyel@hyperbola.info>
