Maintain this project as individual

[Jannik Vogel]

I think this is too hacky for OpenSWE1R and diverges too much from the OpenSWE1R idea.

I should add my typical readme for private projects with donation links and such.
Obviously I should still link to OpenSWE1R and probably also advertise that project in the patched game (with an additional text on the main menu for example).

I should also add a "thanks" for work done by @jordan4302 and ask about sharing donations and permissions in this context.

Sort-of done
