`tn_normalize_sentence` does not exist in Rust

[hongbo-miao]

Currently

use text_processing_rs::tn_normalize_sentence;

fn main() {
    let normalized_text = tn_normalize_sentence("I have twenty one apples.");
    println!("{normalized_text}");
}

gives error

error[E0432]: unresolved import `text_processing_rs::tn_normalize_sentence`
 --> src/main.rs:6:5

normalize_sentence exists, however tn_normalize_sentence seems not exist.
