Allow cross-site usage of the options cookie

The [SameSite cookie](https://web.dev/samesite-cookies-explained/) setting (which now defaults to `lax` in Chrome) limits access of the `options` cookie.
This breaks [command.games](https://github.com/davidtorosyan/command.games), which depends on this cookie. 
This change sets `sameSite` to `none`, which should fix the plugin.

See issue #58.
