Rust version of 59 Rocket

[DLotts]

I am learning Rust and I learned to program from this book on the TRS-80!
Lunar lander (Rocket) was one of my favorites.
I read your post:
"create other implementations and link them from the readme.md for the game"
I am not sure what you mean there. I did it like another rust port that I saw, I hope I got it right.

Edit: I read your recommendations from the root README.md after I finished coding it, so for example: I did not add comments. I used original single letter capital variable names. Otherwise I feel it is a good combination of normal Rust AND maps to the original code nicely.
Let me know if you want me to spruce it up to your recommendations.

Looks good! I would spruce it up a bit as you have time! 🙏
