+ generalize gamma LUT file extension checking, by replacing the "full file ext checking" with "file ext ending chars checking", to handle both "utm*" and "eqa*" prefix, such as .UTM_TO_RDC, .eqa_2_rdc, as provided by the various gamma users (GAMMA is annoying), in the following scripts: - utils.readfile - utils.writefile - prep_gamma + utils.readfile.read_binary(): convert ~pi value to zero while read phase from cpx file - convert ~pi value to zero while read phase from cpx file, as it sometimes happens to gamma products, probably due to the limited numerical precision of the complex data file, such as .int file. - light refactoring while calling np.fromfile(), to improve the readability + utils.readfile.read_binary_file(): for roipac processor, which is the default one if not specified, honor the metadata file for the following attributes if they exist, instead of using the hardwired value, which is the same as the default ones: - INTERLEAVE - BANDS - BYTE_ORDER - DATA_TYPE + docs/api/attribute.md: add BYTE_ORDER for gamma + dosc/api/data_structure: add file name convention
+ objects/resample.py: fix a bug for `geocode.py --bbox` option while geocoding gamma products with customized SNWE from --bbox option, the output dest_box does not start from 0, thus, should use box[3/4] directly, instead of box[3]-box[1] and box[2]-box[0] + cli/subset: check input file exsitence + view.py --coord: update help msg to avoid potential confusions by updating utils.arg_utils.add_figure_argument() + view.py --coord: set the other choices as yx, instead of radar, and keep radar still in the loop for backward compatiability
