/**
 * 时间戳和日期相互转换
 * @param {number|string}  time 时间戳或日期（日期示例:2022-08-10或者2022/08/10 16:37:51）
 * @param {boolean} isDisplayDate  是否仅展示年月日 默认true
 * @returns {string|number}
 * @example
 * dateAndTimestampConversion(1660120671762) // '2022-08-10'
 * dateAndTimestampConversion(1660120671762,false) // '2022-08-10 16:37:51'
 * dateAndTimestampConversion('2022-08-10 16:37:51') // 1660120671000
 * dateAndTimestampConversion('2022/08/10 16:37:51') // 1660120671000
