…st one + objects.cluster.split_box2sub_boxes(): if the last step is too small (<5% or <5 pixels), merge it to the 2nd last one. This change is necessary to avoid the reshaping error when the step size of the last sub-box is 1, turning a 3D matrix into 2D, thus, resulting in a reshape error, such as in diff.py. + update the num_box based on the returned box_list from split_box2sub_boxes(), as it maybe different from the initially input num_box. This is similar to insarlab#940, but search and update all the other instances.
+ save_gdal.py: convert numpy array from boolean to uint8, as GDAL does not support boolean data type, such as used in all the mask files.

…` for tiny last step (insarlab#1024) + `save_gdal.py`: convert numpy array from boolean to uint8, as GDAL does not support boolean data type, such as used in all the mask files. + `objects.cluster.split_box2sub_boxes()`: avoid the tiny last step (<5% of the normal step, or <5 pixels), by merging it into the 2nd last one. This happens to very large datasets sometimes. For example, if the last step has a size of 1, a 3D matrix will be turned into 2D, resulting in a reshape error. + `objects.cluster.split_box2sub_boxes()`: return the final number of sub_boxes, in addition to the current list of sub_boxes, for easier usage (as it may be different from the initial num_box as identified in insarlab#940). Update the usage in all occurrences: - objects.resample - dem_error - diff - reference_date - timeseries2velocity
