Load the Iris dataset

Returns a dataset with 150 samples and 5 columns:

• sepal_length (f64)
• sepal_width (f64)
• petal_length (f64)
• petal_width (f64)
• species (string: “setosa”, “versicolor”, “virginica”)

Example

use alimentar::datasets::{iris, CanonicalDataset};

let dataset = iris().unwrap();
println!(

    dataset.len(),
    dataset.num_features()
