Materialdesign: Icon to represent agent or spy

[karlsnyder0]

I have:

• [ x ] [Searched all issues](https://github.com/Templarian/MaterialDesign/issues) to make sure there isn't a request for this icon.
• [ x ] [Searched the current library](https://materialdesignicons.com/) to make sure the icon doesn't exist.
• [ x ] Only requested a single icon (or a few near-identical ones) in this issue.

Usage

Inspect, or listen to. For example, to listen in on network packets.

Examples

Include any example images so we know what the icon should look like.

Would incognito work?

[karlsnyder0]

Incognito looks like a vehicle.

[Templarian]

Our current incognito is more for Google Chrome. It's not really a Material Design representation.

[goyney]

It's not even the Chrome image...

[goyney]

I vote for updating ours to the latest Google icon and calling this issue good.

Here is the current version.

The version @nilsfast posted above and a circled variant are both available in Material Icons Extended.

And incognito-off?

[PeterShaggyNoble]

Missed that one, @nilsfast; looks like you edited it in after I read your comment. That one's not included in MIE, no.

[goyney]

incognito and incognito-off have been updated and the circle variants added.
