ADP Mobility Manual CSV to JSON Converter

This script reads the ADP Mobility Manual CSV file, cleans the data,
and outputs a JSON file that can be imported into Odoo's fusion.adp.device.code model.

Usage:
    python import_adp_mobility_manual.py input.csv output.json

Or run without arguments to use default paths.
