Fix circular dependency found by Node.JS 14

[robertkiel]

Istanbul version 0.4.5 seems to produce a circular dependency when using Node.JS 14

(node:23084) Warning: Accessing non-existent property 'VERSION' of module exports inside circular dependency

The problem seems to be that VERSION is loaded before lib/commands/index.js is built and ready to be exported.

Requiring VERSION once it is needed, namely once the help command runs, solves the problem.

Referring to issue hoprnet/hoprnet#1241.

Coverage remained the same at 97.523% when pulling e735f69 on robertkiel:master into bc84c31 on gotwarlost:master.

Same error on Node v.15.5.0. thx for the PR, hoping it will get merged asap

A simpler change is just to read the VERSION from Command defined in line 6:

var Command = require('./index.js'),
...
    // VERSION = require('../../index').VERSION
    VERSION = Command.VERSION,

👍 Can we get this change merged?

@gotwarlost Hello from 2023. Can we please get this merged?

Assuming this repo remains confusingly not archived, from npm's instanbul:

This module is no longer maintained, try this instead: npm i nyc Visit https://istanbul.js.org/integrations for other alternatives.

Looking for a fix on this issue. The nyc command doesn't seem to fix the issue in the babel-plugin-istanbul package, which seems to be the cause of this.

Thanks,
