docs: Given a namespace ID and block number, get the current namespace op (revealed or ready) for it
          if the namespace existed after that block.  Optionally return the namespace
          record even if it's a NAMESPACE_REVEAL and it expired.
  
          Return the dict with the parameters on success.
          Return None if the namespace has not yet been revealed.
