Beatmap leaks memory

[MaxOhn]

import * as fs from 'fs';
import * as rosu from "rosu-pp-js";

const file_path = `/mnt/f/osu!/beatmaps/53.osu`;
const bytes = fs.readFileSync(file_path);

while (true) {
    let beatmap = new rosu.Beatmap(bytes);
}

This MRE currently results in RAM usage steadily climbing up. This issue has most likely to do with rustwasm/wasm-bindgen#3917.

I believe the best "workaround" is to denote very clearly in the readme and documentation to call Beatmap.free manually.
