TFHE/ORE benchmark

A small benchmark suite comparing similar operations in the homomorphic encryption library tfhe to the order revealing encryption library ore-rs.

Running

Run the benchmarks using the following command:

cargo bench

Performance characteristics may change if you target your native CPU. It might be useful to try running the following as well:

RUSTFLAGS="-Ctarget-cpu=native" cargo bench
