Handle multiple prices per item

I have a use case where I am implementing a localised cart where cart items may have a different prices per currency/locale.

Currently items are require to have a single price: number, which limits the possibility of offering multiple prices on cart items.

Yes, the first option worked perfectly! Thank you very much for your patience and help!!

@notrab Happy to add a PR that implements prices: ItemPrice[].

interface ItemPrice {
  amount: number,
  [key: string]: any
}

My concern is then how to we calculate totals on a per currency basis, unless we make currency required.

I guess those total functions need to be updated to also reflect multiple price support.
