Make node-serialport context-aware

[clementAC]

I'm not an expert on this.

I'm using node-serialport in electron. From what I know libraries like node-serialport may be loaded multiple times in different context.

In the last "LTS" electron version 7.X there is a deprecation warning concerning non context aware libraries.

Here is the related content I found about this context aware "problem" :

• [Discussion] Requiring Native Modules in the Renderer Process to be NAPI or Context Aware electron/electron#18397
• https://nodejs.org/docs/latest-v12.x/api/addons.html#addons_context_aware_addons

Just posting this issue to discuss about the topic and see how I can help despite the fact that i'm not a C/C++ expert

It would be great to make this happen so the modules can still be used in the rendering process if no external content is being used.

This would help with workers too #1938

Looking for volunteers.
