Add argument parsing for --calendar and remove deprecated cgi module

[monteship]

This commit add the argument parsing for the --calendar option and removes the deprecated cgi module. The --calendar argument is now parsed separately and removed from sys.argv before parsing the remaining arguments. This ensures that the --calendar argument is only used to set the calendar and then ignored. Additionally, the cgi module import has been replaced with urllib.parse to avoid deprecation warnings.

This arg is added to have ability to have several waybar modules.

this looks really good, thank you!

i am not sure i understand about this part:

The --calendar argument is now parsed separately and removed from sys.argv before parsing the remaining arguments. This ensures that the --calendar argument is only used to set the calendar and then ignored.

why does it need to be only set by the calendar and then ignored? what kind of issues is there if you just add it to the argument parsing? maybe i am missing something there?

you only need to add this argument:

    parser.add_argument(
        "--calendar",
        help="Specify the calendar to use",
        default=DEFAULT_CALENDAR,
    )

and you don't need to redefine a new argparse

`parser.add_argument(
"--calendar",
help="Specify the calendar to use",
default=DEFAULT_CALENDAR,
)

initial_args, _ = parser.parse_known_args()

calendar = initial_args.calendar

parser.add_argument(
    "--gcalcli-cmdline",
    help="gcalcli command line",
    default=GCALCLI_CMDLINE.format(calendar=calendar),
)`
