slicecreates a copy of arraybuffer due to which unnecessary memory is allocated, if we replace it withsubarraywhich only creates a read only view, it lowers the memory usage by 100%.In this case
this.datais only read from so imo its safe to usesubarraybut might need more testing of edge cases.I tested for a sample ~2gb file in demo, earlier memory usage was around ~6.5gb, after the change it dropped to ~4.5gb, almost the same amount as that of file size
