Objectivo
Desarrolle un programa Python para mejorar la clase TextToHTML agregando la capacidad de guardar sus resultados en un archivo de texto. Incluya un método llamado save_to_file, que tomará el nombre del archivo como argumento y escribirá en él el contenido HTML generado.
Sugerencia: use un mecanismo de escritura de archivos como open() con el modo establecido en "w" para manejar las operaciones de archivo.
