Add persistent toasts

Sometimes we need to show toast until it’s dismissed by user or programmatically. E. g. connection lost and notification is shown until it’s back online. Or some long or slow process happens.

It is not always possible to use toast.promise for that. Currently I use very long duration to simulate persistent toast.

Is it possible to add persistent toast, which doesn’t have any timers inside them? Then it would possible to do:

const id = toast('No connection.', { persistent: true });

toast('Connected.', { id, persistent: false })

Thanks for the feedback! I agree with you, using Infinity seems like the more intuitive API. Will update and merge the PR 😃

@timolins I think it would be better to just do if (!isFinite(duration)) { don't set timeout } and keep using the { duration: Infinity } API.
