Symlink Tarkov and SPT installs to save space when testing.

SPT.Symlink.py

"""
This script requires Python 3.11 or later

Put it in a directory alongside a folder named `meta`, it should have a structure like the following:
├── newlink.py
└── meta
    ├── game
    │   └── 14.1.2.29197
    │       ├── EscapeFromTarkov_Data

    │       └── UnityPlayer.dll
    ├── spt

    └── sptSettings
        ├── Control.ini
        ├── Game.ini
        ├── Graphics.ini
        ├── PostFx.ini
        └── Sound.ini

The only names that matter are `meta`, `game`, `spt`, and `sptSettings`

The folders in `game` should contain patched versions of EFT without SPT installed.

The folders in `spt` should contain extracted SPT releases.

`sptSettings` should be copied from an existing install's `user` folder.
This will optionally be linked so all installs share the same graphics and keybind settings.
If using this, select "No" when the launcher asks to copy settings from Live.

The new instance will be created next to the `meta` folder.

Note when using this script editing files in `SPT_Data/Server/configs` will affect all installs.
It's recommended to use server mods to edit those instead.
