Request for support of Sandia's `FARAD SAR DATA COLLECTION` `Complex SAR Data` format

[eleehiga]

Trying to read a complex SAR data file similar to:

from sarpy.io.complex.converter import open_complex

reader = open_complex('FARAD_X_BAND/20151027_1027X04_PS0010_PT000001_N03_M1_CH0_OSAPF.ntf ')

This yields the error sarpy.io.general.base.SarpyIOError: Unable to determine complex image format. The data is from here: https://www.sandia.gov/files/radar/complex-data/FARAD_X_BAND.zip and from this website here: https://www.sandia.gov/radar/pathfinder-radar-isr-and-synthetic-aperture-radar-sar-systems/complex-data/. Have tried the GFF reader, as this data is from Sandia, here: https://sarpy.readthedocs.io/en/latest/io/complex/gff.html but that still led to errors. Therefore was wondering if you guys could please support Sandia's FARAD SAR DATA COLLECTION Complex SAR Data format and the beginning of this file is here:

This file is readable with MATLAB with this reader here: https://github.com/ngageoint/MATLAB_SAR/blob/master/IO/complex/nitf/open_cnitf_reader.m. Therefore was wondering if you guys could please implement this reader in sarpy.
