How to use the cspell-trie-lib.serializeTrie function in cspell-trie-lib

notify('Create Trie', !!outputFile);
        const pOutputStream = createWriteStream(outputFile);
        notify(`Generating...`, !!outputFile);
        const lines = await fileToLines(filename);
        const toLower = lowerCase ? (a: string) => a.toLowerCase() : (a: string) => a;

        const wordsRx = lines
            .map(toLower)
            .map(a => a.trim())
            .filter(a => !!a);

        notify('Processing Trie');
        const root = wordsRx.reduce((node: Trie.TrieNode, word: string) => Trie.insert(word, node), {} as Trie.TrieNode);

        notify('Export Trie');
        const serialStream = iterableToStream(Trie.serializeTrie(root, (base - 0) || 32));
        const outputStream = await pOutputStream;
        return new Promise((resolve) => {
            serialStream.pipe(outputStream).on('finish', () => resolve());
        });
    });

export async function compileTrie(words: Sequence, destFilename: string, options: CompileTrieOptions): Promise {
    log('Reading Words into Trie');
    const base = options.base ?? 32;
    const version = options.trie3 ? 3 : 1;
    const destDir = path.dirname(destFilename);
    const pDir = mkdirp(destDir);
    const root = normalizeWordsToTrie(words);
    log('Reduce duplicate word endings');
    const trie = consolidate(root);
    log(`Writing to file ${path.basename(destFilename)}`);
    await pDir;
    await writeSeqToFile(Trie.serializeTrie(trie, { base, comment: 'Built by cspell-tools.', version }), destFilename);
    log(`Done writing to file ${path.basename(destFilename)}`);
}
