Description

I don't know if this is a Support request or a Feature Request:

I'm under a business requirement that demands a custom cookie expiration. I searched for an option in LocalizeParser class to customize the COOKIE_EXPIRY variable declared in localize-router.parser.js. I'm using the language detection of the LocalizParser, the cookies option, with the private function _cacheWithCookies that uses the COOKIE_EXPIRY.

There is a way to customize that variable at the init of the LocalizeParser?

If not, I think the customization of the cookie expiry is a nice feature to include in the library.

Thanks for the job!
