Add Linux patcher script

[rakelley]

I've put together a basic patching script to save Linux users like me a little time/research. I figured the best option for portability was to compile dtkit-patch locally rather than have you include and test another binary in your releases, which adds dependencies on cargo and git, but that shouldn't be a significant hurdle for any Linux user.

If you have any changes, please let me know. I didn't find a public repo for the docs at https://dmf-docs.darkti.de/index#/installing-mods but would be happy to submit a PR for that as well if it exists.

For people stumbling on this PR request, install rustup (toolchain for the programming language Rust) and it will include cargo which is Rust package manager

Would a simple script containing wine ./tools/dtkit-patch.exe --toggle ./bundle not be sufficient?
While a native dtkit-patch is nice, you need wine/proton for the game anyways.

This worked perfectly for me, but I already had rust installed. I would agree that if wine must already be installed on the system and available on a users path to have the game work that the wine approach would be superior.

We should just vendor the linux dtkit-patch binary rather than building it on demand

I've updated the script to prefer using wine, keeping the native patcher only as a fallback or manual override via -f|--force
