Add exe easier to use for multiple builds option

[BialySztorm]

what about creating an exe with something like this:

import os
import sys


def run3dsconv():
    if not os.path.exists("cias"):
        os.makedirs("cias")
    input_directory = "roms"
    for root, dirs, files in os.walk(input_directory):
        for file in files:
            if file.endswith(".3ds"):
                input_path = os.path.join(root, file)
                output_dir = "cias"
                print("Converting", input_path, "to", output_dir)
                os.system("python 3dsconv.py --output=\"" + output_dir + "\" --boot9=\"boot9.bin\" \"" + input_path + "\"")


if __name__ == "__main__":
    if not os.path.exists("roms"):
        print("Error: roms directory not found")
        os.makedirs("roms")
        sys.exit(1)
    if not os.path.exists("boot9.bin"):
        print("Error: boot9.bin not found")
        sys.exit(1)
    run3dsconv()

so you can simply run the code and everything will be done automaticaly without any data parsing in
