binance: parse .expiry separate from .venue

Apparently they're being massive cucks and changing their futes pair
schema again now adding a `NEXT_QUARTER` contract type which we weren't
handling at all. The good news is falling back to an old symcache file
would have prevented this from crashing.

Add a new `FutesPair.expiry: str` field so that `.bs_fqme` can simply
call it during the summary FQME-ification output rendering..
