/**
 * 取代字串，由c內大括號會標記為被取代的{key}，再由物件o的key所對應value進行取代，而各value皆需要為有效字串
 *
 * Unit Test: {@link https://github.com/yuda-lyu/wsemi/blob/master/test/replaceObj.test.mjs Github}
 * @memberOf wsemi
 * @param {String} c 輸入要被取代的字串
 * @param {Object} o 輸入用來取代的key,value物件
 * @returns {String} 回傳取代後字串
 * @example
 *
 * console.log(replaceObj('1.25abc中文', { '5a': '0', '中': '英' }))
 * // => '1.20bc英文'
