Get ISO

The default method assumes the ISO can be accessed as if it were an attribute with name iso (e.g. x$iso). The method for CurrencyPair concatenates the ISOs of the constituent currencies (e.g. iso(AUDUSD()) returns "AUDUSD") while the methods for CashIndex and IborIndex return the ISO of the index's currency.

# S3 method for IborIndex
