Description of proposed changes

Modified asc_desc2horz_vert.py to specify different dataset other than the same dataset for the two input files when decomposing to horizontal and vertical displacement/velocity.

Summary by Sourcery

Allow users to specify a different dataset name for each input file when converting ascending/descending measurements to horizontal and vertical components

New Features:

• Accept multiple dataset names via the -d/--dset CLI option to map one dataset per input file
• Use each provided dataset name when reading attributes and data for its corresponding file instead of assuming a single common dataset

Enhancements:

• Maintain backward compatibility by falling back to the original single-dataset behavior if only one name is given

Reviewer's Guide

Enable per-file dataset selection by converting the --dset/ ds_name parameter to a list, updating the CLI to accept multiple dataset names, and adjusting internal logic to read attributes and LOS data using the corresponding dataset entry for each input file.

File-Level Changes

Change	Details	Files
Extend CLI to accept multiple dataset names for input files	Change --dset parser to use nargs='+' and produce a list of dataset names Update ds_name parameter type to list of strings	src/mintpy/cli/asc_desc2horz_vert.py
Update dataset handling in asc_desc2horz_vert.py to support per-file datasets	Use ds_name[0] for overlap attribute calculation Introduce dataset_order = len(ds_name) for conditional logic Branch LOS data read: iterate per file index to pick ds_name[i], fallback to original ds_name for single entry	src/mintpy/asc_desc2horz_vert.py
