/**
 * The NITF (National Image Transition Format) format is a file format developed by the U.S. Government for
 * storing imagery, e.g. from satellites.
 * 
 * According to the [foreword of the specification](https://web.archive.org/web/20181105050336/https://www.gwg.nga.mil/ntb/baseline/docs/2500c/2500C.pdf):
 * > The National Imagery Transmission Format Standard (NITFS) is the suite of standards for formatting digital
 * > imagery and imagery-related products and exchanging them among members of the Intelligence Community (IC) as
 * > defined by the Executive Order 12333, and other United States Government departments and agencies."
 * 
 * This implementation is set to version format (`file_version`) of 02.10 and `standard_type` of `BF01`.
 * It was implemented by [River Loop Security](https://www.riverloopsecurity.com/).
 * @see <a href="https://web.archive.org/web/20181105050336/https://www.gwg.nga.mil/ntb/baseline/docs/2500c/2500C.pdf">Source</a>
