using proxy with fetch
https://www.zenrows.com/blog/node-fetch-proxy#how-to-use-proxy-with-node-fetch
for username and password
https://github.com/TooTallNate/proxy-agents/issues/12


```js
const fetch = require('node-fetch');

const proxyUrl = 'http://proxyserver:port';
const proxyOptions = {
  proxy: proxyUrl,
  headers: {
    'Proxy-Authorization': 'Basic ' + Buffer.from('username:password').toString('base64')
  }
};

fetch('http://url-to-fetch', proxyOptions)
  .then(response => response.text())
  .then(data => {
    console.log(data);
  })
  .catch(error => {
    console.error('Error:', error);
  });

```

Same with curl
`curl -x http://proxyserver:port --proxy-user username:password http://url-to-fetch`
for socks5
`curl -v --socks5 127.0.0.1:1080 https://icanhazip.com`
replace with socks4 for socks4
