Improve project name

[Jesper-Hustad]

The current name bad-light-preview is descriptive, but no longer encompasses the future goal of this project.

The tool is going to include multiple environments and lighting conditions.

In the graphic world this is called mockups, tough I would highly prefer that it did not include mockup in the name (as many non designers may not know what this means).

So here are some ideas for what the name should convey:

• That this is a online tool.
• That it simulates multiple lighting conditions
• That it's for previewing
• That it's for physical print

Doesn't need to include everything ofc. just some general ideas.

Here are some examples: paper-in-situations, preview-environments, view-design-circumstances

Feel free to come up with better suggestions, best one can send PR with the changes in README.md
