What happened?

Description

I've been informed by my client that the UK is missing a state 'Aberdeenshire'. I questioned this with Commerce Guys on the following commerceguys/addressing#226 (comment)

Is this something you guys are able to add? Alternatively, is it possible for me to include this as an option on the site via a custom module using an event?
