使用js 将ETH账户的资产汇集到一个账户

平时如果你需要把多个账户的eth汇集到一个账户，就需要一个个的发送，很麻烦，下面这段脚本可以把多个账户的eth汇集到一个账户
首先安装依赖插件

npm install -save web3@4.0.3
npm install -save @ethereumjs/common@3.2.0
npm install -save sign-tx

如下代码展示如何将
"0x962Ec4fAb7f283051622BE83f9C64c9DD12Ead73",
“0x5960596b614341af474A5bc9E240636687A5aE4E”,
“0x2B5Ae3C44703a7Bde45Da0a189cd74449c4A06ab”,
“0xA4505b256B44c98f9675614D731408f27D186556”,
“0xa4e43e2168B261d227F6216ca4e495516CF8406c”,
“0x7990CA5C9Ad5F1F579df2e3E24dd90305585D7e7” 账户的ETH平均汇集到0x900a2e6B7831e594CC0ec4eBA2dB044a565D38a4
