Split variable lists for IBT and Live modes, add variable types, reformat

[BeardedBeaver]

Add separate variable lists for IBT file and Live modes. Previously there was a single list for Live mode.

Also include information about the variable type and format the rows a bit cleaner.

Dumped with the following script

import argparse

import irsdk  # type: ignore

type_map = {
    0: "irsdk_char",
    1: "irsdk_bool",
    2: "irsdk_int",
    3: "irsdk_bitField",
    4: "irsdk_float",
    5: "irsdk_double",
}


def dump(headers: list[irsdk.VarHeader]) -> None:
    for h in headers:
        t = type_map.get(h.type)
        assert t, f"Unknown type {h.type} for channel {h.name}"
        print(f"{h.name:<40} {h.unit:<20} {t:<20} {h.desc}")


def parse_args() -> argparse.Namespace:
    parser = argparse.ArgumentParser()
    sub = parser.add_subparsers(dest="mode", required=True)

    sub.add_parser("live")

    ibt = sub.add_parser("ibt")
    ibt.add_argument("--file-name", required=True)

    return parser.parse_args()


def main() -> None:
    args = parse_args()

    if args.mode == "live":
        ir = irsdk.IRSDK()
        ir.startup()
        if not ir.is_connected:
            raise RuntimeError("iRacing is not running")
        dump(ir._var_headers)

    elif args.mode == "ibt":
        ir = irsdk.IBT()
        ir.open(args.file_name)
        dump(ir._var_headers)  # type: ignore


if __name__ == "__main__":
    main()

Sorted separately to match the original sorting
