ib.feed: handle fiat (forex) pairs with `Asset`
Also finally adds full `FeedInit` and `MktPair` support for this backend by handling: - all "currency" fields for each `Contract` by constructing and `Asset` and setting the `MktPair.src` with `.atype='fiat'`. - always render the `MktPair.src` name in the `.fqme` for fiat pairs (aka forex) but never for other instruments.account_tests
