Fixed

• Five more bank-stream slices guarded against a corrupt offset table. 0.5.1
  fixed the four columnar sites; the same &stream[record.bank_byte_range(e, b)]
  pattern — a raw slice index with bounds read from the file — remained in
  Event::iter_structures, OwnedEvent::bank (twice) and EventCtx::bank (twice).
  These are the whole-event paths, so they are what a consumer reaches through
  structures(), ev.bank() and the for_each callback: a wider surface than the
  columnar ones. None is returned instead of panicking, which already means "no
  such bank in this event" at every call site.

  After the 0.5.1 fix a downstream fuzz test found the fifth site immediately, so
  the pattern was grepped for rather than the report chased, which found the other
  four at once.
