Create and add a logo for use in the project browser

Problem/Motivation

The Project Browser Initiative wants nice project logos for better UX. The logo will be displayed on the card for your module in the Project Browser (as well as on drupalcode.org as your project avatar, and on drupal.org on your project page).

This module needs a logo for this objective.

Proposed resolution

Create a logo that is 512x512 square dimension in PNG format without animations.
The file size should be 10k or less.
Use a lossy image tool (such as pngquant) to reduce the file size while keeping the image quality at around 80%.
