/**
* 前端讀取Excel檔，前端由input file的檔案取得Uint8Array，並採用動態加載技術
* 若數據格式fmt為csv格式，數據分欄符號為逗號，分行符號為[\r\n]，內容開頭無BOM，方便使用者解析
*
* Unit Test: {@link https://github.com/yuda-lyu/wsemi/blob/master/test/getDataFromExcelFileU8ArrDyn.test.mjs Github}
* @memberOf wsemi
* @param {Uint8Array} u8a 輸入file資料，格式需為Uint8Array
* @param {Object} [opt={}] 輸入設定物件，預設為{}
* @param {String} [opt.fmt='ltdt'] 輸入數據格式，可有'ltdt','csv','array'，預設為'ltdt'
* @param {Boolean} [opt.valueToString=true] 輸入數據是否強制轉字串布林值，預設為true
* @param {String|Object|Array} pathItems 輸入資源字串、字串陣列、物件、物件陣列
* @returns {Promise} 回傳Promise，resolve回傳數據陣列，reject回傳錯誤訊息
* @example
* need test in browser
