* 给异步函数封装重试逻辑
* @param {Object} options 重试逻辑入参
* @param {Object} options.retryFunction 需要封装的异步函数
* @param {Object} options.settings 重试属性
* @param {Number} [options.settings.retries = 5] 重试次数
* @param {Number} [options.settings.timeout = 1000] 重试间隔
* @param {onErrorCallback} options.onError 重试错误回调
* @param {onRetryingCallback} [options.onRetrying] 重试后的回调
* @param {Object} options.context 上下文，可选
* @returns {Function} 封装后的函数
* @example
* const getUserMedia = promiseRetry({
