Support npm config params

[vitalets]

In our scripts we are using $npm_config_xxx params.
for example:

"scripts": {
    "zip": "cd $npm_config_outdir && zip -rT $npm_config_outzip .",
    "crx": "crx pack $npm_config_outdir",
    "zip-crx": "npm run zip && npm run crx",
}

We can run such scripts via:

npm run zip-crx --outdir=dist --outzip=archive.zip

it would be great if npm-run-all support such npm params and not confuse it with own params or command own params.
Currently I get error:

ERROR: Invalid Option: --outdir=dist

Thank you for this issue.

I have not been aware of that feature of npm. (though npm-run-all supports $npm_package_config_xxx variables since #13).
I will do.

Thanks a lot for quick reply and actions!
When you plan to release?

[mysticatea]

Just now, I released v3.1.0 😄
Please tell me if there are problems.

Thank you!

This needs to be reverted. it was poorly planned and thought out.
