Write a version-00 traceparent — for an outbound call that continues this run's trace. Both ids must be W3C
ids and flags a byte of 2 lowercase hex (refused by name otherwise, like a parse); sampled, when given,
sets or clears bit 0 of the flags. formatTraceparent(parseTraceparent(h)) is h for any valid version-00 h.
