/**
 * 一般字串轉SHA512字串
 * Secure Hash Algorithm 512位
 *
 * Unit Test: {@link https://github.com/yuda-lyu/wsemi/blob/master/test/str2sha512.test.mjs Github}
 * @memberOf wsemi
 * @param {String} str 輸入一般字串
 * @param {Boolean} [base64=false] 輸入是否轉為base64字串，預設為false
 * @returns {String} 回傳經SHA512轉換後字串
 * @example
 *
 * console.log(str2sha512('test中文'))
 * // => 'ab43333a01571e767a2eb15460c270fa123964c121b88c73e274a211d6e2cf98b10d89220e8d04e2fc573354da93400f3255e94d445dc956e177aa4201a4fc30'
