normalize_sentence failed on "United seven eighty eight"

[hongbo-miao]

I am using text-processing-rs version 0.1.0

Case 1 (Correct): Using normalize:

use text_processing_rs::normalize;

fn main() {
    let normalized_text = normalize("United seven eighty eight");
    println!("{normalized_text}"); // 788
}

Case 2 (Incorrect): Using normalize_sentence:

use text_processing_rs::normalize_sentence;

fn main() {
    let normalized_text = normalize_sentence("United seven eighty eight");
    println!("{normalized_text}"); // United 95
}

This gives me United 95, however, I expect it to be United 788
Seems it tries to add 7 + 88 = 95

It would be great to support this case, as this way of speaking is common in aviation. Thanks! ☺️
