/**
* 使用rollup轉譯外部指定的核心分析程式碼檔案，並封裝至前端web worker與後端worker內
*
* @param {Object} opt 輸入設定物件
* @param {String} opt.name 輸入模組名稱字串，將來會掛於winodw下或於node引入使用
* @param {String} [opt.type='object'] 輸入模組類型字串，可選'function'、'object'。若使用'function'，於初始化後可呼叫terminate銷毀；若使用'object'，預設execObjectFunsByInstance為true，執行完指定函數後亦自動銷毀，若改execObjectFunsByInstance為false，就一樣得於初始化後呼叫terminate銷毀。回傳函數或物件。轉譯後會掛載模組名稱至window下，若type使用'function'時則window['模組名稱']為函數，得自己初始化才能呼叫其內函數或監聽事件；若type使用'object'時則window['模組名稱']為物件，可直接呼叫其內函數預設'object'
* @param {Array} opt.funNames 輸入模組可被呼叫的函數名稱陣列
* @param {Array} [opt.evNames=[]] 輸入模組可監聽的函數名稱陣列，預設[]
* @param {String} opt.fpSrc 輸入原始碼檔案位置字串
* @param {String} opt.fpTar 輸入轉譯完程式碼檔案儲存位置字串
* @param {String} [opt.nameDistType=''] 輸入轉譯檔案名稱格式字串，可選'kebabCase'，預設''
* @param {Function} [opt.hookNameDist=null] 輸入強制指定轉譯檔案名稱函數，預設null，會複寫nameDistType之處理結果
* @param {String} [opt.formatOut='es'] 輸入欲轉譯成js格式字串，可選'umd'、'iife'、'es'，預設'es'
* @param {String} [opt.targets='new'] 輸入轉譯等級字串，可選'new'、'old'，預設'new'
* @param {String} [opt.runin='both'] 輸入執行環境字串，可選'both'、'nodejs'、'browser'，預設'both'
* @param {Boolean} [opt.bNodePolyfill=false] 輸入轉譯是否自動加入Nodejs polyfill布林值，主要把Nodejs語法(例如fs)轉為瀏覽器端語法，預設false
* @param {Boolean} [opt.execFunctionByInstance=true] 輸入若模組類型為物件type='function'時，是否將function視為使用獨立實體執行並自動銷毀實體布林值，例如原模組就是一個運算函數，不需要回傳eventemmitter監聽事件，預設true
* @param {Boolean} [opt.execObjectFunsByInstance=true] 輸入若模組類型為物件type='object'時，各函式是否使用獨立實體執行布林值，例如使用到stream的各函式會因共用同一個實體導致降速，故各函數需自動有各自實體，預設true
* @param {Boolean} [opt.bMinify=true] 輸入轉譯檔案是否進行壓縮布林值，預設true
* @param {Boolean} [opt.keepFnames=false] 輸入當轉譯檔案需壓縮時，是否保留函數名稱布林值，預設false
* @param {Array} [opt.mangleReserved=[]] 輸入當轉譯檔案需壓縮時，需保留函數名稱或變數名稱陣列，預設[]
* @param {Array} [opt.mainFields=null] 輸入取用套件內環境入口時，可強制給予循序入口陣列，各入口可選'browser'、'module'、'main'，給予null則代表用rollup內建，預設null
* @param {Object} [opt.globals={}] 輸入指定內外模組的關聯性物件，預設{}
* @param {Array} [opt.external=[]] 輸入指定內部模組需引用外部模組陣列，預設[]
* @param {Boolean} [opt.bLog=true] 輸入是否顯示預設log布林值，預設true
