Pass process arguments and environment variables to node.script object

[ronenlh]

Nature of issue?

• Found a bug in an example
• Existing example enhancement
• Suggest a new example

Existing example enhancement details:

Existing examples such as freesound, twitter, and giphy, use process.env through dot-env to access credentials.
There are no examples which use process.argv.

New example details:

There should be an example on how to pass arguments to node.script from inside the patcher (such as an inlet), which can then be retrieved through process.argv.
There should also be an example on how to pass environment variables to node.script, set in the patcher (such as from the inspector), which can be retrieved through process.env.
