Add more information to adb_t

In this case, add a vector to store track offsets.

WARNING WARNING WARNING: unlike trackOffsetTable, this is a raw off_t in
bytes of the feature data: in other words, it already has sizeof(double)
and dbH->dim in it.  (I think this is probably minimally unsurprising in
the long run, but as I convert stuff there might well be errors creeping
in...)

    return 1;
  }

  adb->header->flags |= O2_FLAG_POWER;
