Update merge.py

Modifications
Introduced the argparse module to parse command-line arguments
Converted previously hardcoded source folder paths, output folder path, max_dim, and FPS values to configurable command-line parameters
Important Note
Note: When merging datasets, the FPS for each collected task must be identical to ensure data synchronization and consistency
