Update 3DMigotoLoader.exe and .py with d3dx.ini config variable reading

[kvnxiao]

I noticed that the launch parameter in d3dx.ini wasn't working to auto-launch the game.

The pyinstaller built exe and the python script should be updated to read from the ini with a simple change to the python script. And instead of hardcoding StarRail.exe we should probably also use the target value from the ini as well.

import psutil
from pyinjector import inject
import re

AUTO_LAUNCH_REGEX = re.compile(r"^launch\s*=\s(.*)$")
TARGET_REGEX = re.compile(r"^target\s*=\s(.*)$")


def _load_config() -> tuple[str, str]:
    auto_launch: str = ""
    target_proc: str = ""
    with open("d3dx.ini", "r") as f:
        for line in f.readlines():
            m = AUTO_LAUNCH_REGEX.match(line)
            if m and not auto_launch:
                auto_launch = m.group(1)
            m = TARGET_REGEX.match(line)
            if m and not target_proc:
                target_proc = m.group(1)
    return auto_launch, target_proc


def main():
    auto_launch, target_proc = _load_config()
    if auto_launch != "":
        print(f"Launching ${auto_launch}...")
        psutil.Popen(auto_launch)
    print("Waiting for program...")
    # Iterate over all running process
    while True:
        for proc in psutil.process_iter():
            try:
                if proc.name() == target_proc:
                    print(f"Found {target_proc}")
                    print(proc.name(), proc.pid)
                    inject(proc.pid, "d3d11.dll")
                    return
            except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):
                pass


if __name__ == "__main__":
    main()
