  @brief    Compute the MD5 hash of data zones in a FITS file.
  @param    filename    Name of the FITS file to examine.
  @return   1 statically allocated character string, or NULL.

  This function expects the name of a FITS file.
  It will compute the MD5 hash on all data blocks in the main data section
  and possibly extensions (including zero-padding blocks if necessary) and
  return it as a string suitable for inclusion into a FITS keyword.

  The returned string is statically allocated inside this function,
  so do not free it or modify it. This function returns NULL in case
  of error.
