Make module context-aware #101

Description

I've been experimenting with worker threads in node.js recently and noticed that the node-oniguruma module does not appear to be context-aware. In other words, the module will load/instantiate once, but as soon as another thread attempts to require oniguruma for it's own use, the following error is thrown:

Error: Module did not self-register.
    at Object.Module._extensions..node (internal/modules/cjs/loader.js:840:18)
    at Module.load (internal/modules/cjs/loader.js:666:32)
    at tryModuleLoad (internal/modules/cjs/loader.js:606:12)
    at Function.Module._load (internal/modules/cjs/loader.js:598:3)
    at Module.require (internal/modules/cjs/loader.js:705:19)
    at require (internal/modules/cjs/helpers.js:14:16)

Steps to Reproduce

In main thread...

const {Worker} = require('worker_threads');
var worker1 = new Worker('./child-thread.js'); 
var worker2 = new Worker('./child-thread.js');
// etc.

In child-thread.js...

{OnigRegExp, OnigScanner} = require 'oniguruma'
scanner = new OnigScanner(['c', 'a(b)?'])
// etc.

Expected behavior:

No error

Actual behavior:

Error
