/**
 * 依照指定字串分割Docx檔
 *
 * @param {String} fpIn 輸入來源Html檔位置字串
 * @param {String} strSep 輸入內文會提供之分割字串
 * @param {String} fdOut 輸入轉出Docx檔位置字串
 * @param {Object} [opt={}] 輸入設定物件，預設{}
 * @param {Integer} [opt.padZero=0] 輸入是否補0位數整數，例如padZero=3時檔名會變成001.docx，預設0
 * @returns {Promise} 回傳Promise，resolve回傳成功訊息，reject回傳錯誤訊息
 * @example
 *
 * import w from 'wsemi'
 * import WDocxSplit from './src/WDocxSplit.mjs'
 * //import WDocxSplit from 'w-docx-split/src/WDocxSplit.mjs'
 * //import WDocxSplit from 'w-docx-split'

 *     let opt = {
 *         padZero: 3,
 *     }
 *
 *     let r = await WDocxSplit(fpIn, strSep, fdOut, opt)
