Generating Sparse Embeddings

// With default InitOptions
let bm42 = BM42::try_new(Default::default()).unwrap();

// With custom BM42Options
let bm42_options = BM42Options {
    alpha: 0.5,
    show_download_progress: true,
    ..Default::default()
};

let texts = vec![
    "It's a truth universally acknowledged that a zombie in possession of brains must be in want of more brains.",
    "We're not in Infinity; we're in the suburbs.",
    "I was a thousand times more evil than thou!",
    "History is merely a list of surprises... It can only prepare us to be surprised yet again.",
