    @package
    Generate a CSV BOM for use with JLCSMT service.
    Components are sorted by ref and grouped by value with same footprint
    Fields are (if exist).
    LCSC Part numbers are copied from the "LCSC Part" field, if exists.
    It is possible to hide components from the BOM by setting the 
    "JLCPCB BOM" field to "0" or "false".

    Output fields:
    'Comment', 'Designator', 'Footprint', 'LCSC Part #'

    Command line:
    python "pathToFile/bom_csv_jlcsmt.py" "%I" "%O.bom.csv"
