/**
 * 通過Pyodide執行Python程式碼，採用動態加載技術
 *
 * Unit Test: {@link https://github.com/yuda-lyu/wsemi/blob/master/test/execPyodideDyn.test.mjs Github}
 * @memberOf wsemi
 * @param {Object} [opt={}] 輸入設定物件，預設{}
 * @param {Array} [opt.pkgs=[]] 輸入Python引用已安裝套件字串陣列，例如為'scipy'、'numpy'等，預設[]
 * @param {Array} [opt.imps=[]] 輸入Python引入(import)的字串陣列，例如為['import scipy','import numpy']等，預設[]
 * @param {Array} [opt.inps=[]] 輸入輸入數據陣列，例如為[123,'abc']等，預設[]
 * @param {String} [opt.content=''] 輸入執行程式核心字串，若要使用inps則使用'rIn數字'，數字由1至inps的長度n，回傳使用'ret'接收，例如ret = fun(rIn1,rIn2,...rInn)，預設''
 * @param {String|Object|Array} pathItems 輸入資源字串、字串陣列、物件、物件陣列
 * @returns {Number|String|Boolean|Array|Object} 回傳運算結果資料
 * @example
 *
