Reorganize Rust Structure

[mariari]

The current structure of having Sudoku folder with the risc0 code was fine before, however I wish to scale up the repo, and have multiple similar folders per idea. Thus I propose the following folder structure

• Program Name [Sudoku]
  • Approach Name with relevant code [Risc0, Halo2, Alucard, etc]
    • Code with an explicitly exported module
• Benchmark (This contains all benchmarks which can be run. A Test property will be had so each benchmark can be run standalone)

Satisfies and modifies the desired structure a bit.

    ├── lib.rs
    └── main.rs

├── README.md
└── src
    ├── lib.rs
    └── main.rs
src
├── main.rs
└── my_benchmark.rs

I will leave this issue open as I believe each directory should have their own benchmarking library, and exported such that the src/main.rs can run all the benchmarks together under 1 command and folder output.
