how require file from memfs in vm2?

[i5ting]

use require.customRequire code here:

const { NodeVM } = require('vm2');
const { fs, vol } = require('memfs');
const { patchRequire } = require('fs-monkey');

vol.writeFileSync('/index2.js', 'console.log("hi world")');
vol.writeFileSync('/index.js', `require('/index2');console.log("hi world")`);

patchRequire(vol); // new require

const vm = new NodeVM({
    require: {
        external: true,
        root: process.cwd(),
        customRequire: require
    }
});

vm.run(`
    require('/index'); 
`, 'test-with-memfs.js');

This is currently not supported. The customRequire is not used for resolving the files but the filesystem is currently used.
