  extract native/orig header return associative array<BR>

  the header is passed as text (lopped off top of a sisu markup file until the
  required first heading ^A~), determine whether is a native header or sdlang one
  with a regex check if whether it contains the "native header" required tag/field
  @title: then process accordingly as a "native header" or "sdlang header"
  converting the metadata and make instructions to a common json format used by
  program internally. Moved to associative array.
