Variable width

[ahopkins]

Nice work on this package. Exactly what I needed.

One thing that would be nice would be the ability to control the width. 40vw can be pretty big in some cases, and in other it would be nice to have a fixed size. Of course it can be done with a wrapper component and overriding the CSS, but it can get messy.

@ahopkins I agree. It could be passed as an option to the notification (I'd also consider wrapping the display duration up in this options object as well). I'd be happy to accept a PR on this if you fancy having a go.

I was having the same issue and gave it a shot. Heres the PR: #7
