Update Benchmarks to include warmup and higher sample size

[infosechoudini]

In the Rust portion of the repo under benches, we should implement criterion in a way that allows a higher warmup of the CPU (3s to 5s) before sampling. In addition, we should increase the sample size from 100 -> 150 and bootstrap samples to 100,000 to have a better idea of deviations.

// Needed for Criterion Warmup
use std::time::Duration;

 // Old Benchmark Code Here //

// remove the following
//criterion_group!(benches, session_encrypt, session_encrypt_decrypt);

criterion_group!(
    name = benches;
    config = Criterion::default()
        .warm_up_time(Duration::from_secs(5))
        .measurement_time(Duration::from_secs(10))
        // degree of noise to ignore in measurements, here 1%
        .noise_threshold(0.01)
        // likelihood of noise registering as difference, here 5%
        .significance_level(0.05)
        // likelihood of capturing the true runtime, here 95%
        .confidence_level(0.95)
        // total number of bootstrap resamples, higher is less noisy but slower
        .nresamples(100_000)
        // total samples to collect within the set measurement time
        .sample_size(150);
    targets = session_encrypt, session_encrypt_decrypt
);

criterion_main!(benches);
