- @tryghost/error constructors take an object, not a string - the expectation is that message, context & help should all be set
- This does the bare minimum and just ensures message is set correctly

We want to be able to use the OfferName as the name property for a
Stripe Coupon - which has a maximum character length of 40.

This adds the concept of "Value Objects" to an Offers properties,
allowing us to move validation out and ensure that an Offer will only
ever have valid properties, without having to duplicate checks - or
leave them to the persistent layer. This means we can fail early, as
well as write unit tests for all of our validation.
