Add social preview icon/logo to ICU4X repo

[nciric]

One would upload image here - https://github.com/unicode-org/icu4x/settings

I'll try doing something in Photoshop - will ask for approval from team before uploading.

From the settings page:
"Upload an image to customize your repository’s social media preview.

Images should be at least 640×320px (1280×640px for best display)."

Proposal (PNGs) for the logo. WDYT?

First proposal:
Stylized with no obvious ICU4X wording, but all the parts are there. X, I, 4, C/U in the curve.

Second proposal:
I, X and 4 are hidden in the drawing, CU is spelled out. Little dot on top adds interest + makes i more visible.

To me, the top requirements for a logo are:

1. Clear at all sizes, including as small as a browser favicon
2. Clean lines and edges
3. Unique, memorable, self-explanatory, and recognizable

The plain ICU logo meets these requirements. You can see it here: http://site.icu-project.org/

The first proposal for the ICU4X logo is okay on criterion 1 and, after conversion to an SVG, criterion 2, but doesn't speak to me on criterion 3: it's not very unique, memorable, self-explanatory, or recognizable.

The second proposal won't be good scaled down to small sizes, so doesn't meet criterion 1 for me. It would probably be okay on criterion 2 after conversion to an SVG. On criterion 3, I'd say the it is unique, memorable, and recognizable, but not very self-explanatory (it looks more like "4CU" than "ICU4X").

That's one way to look at the logo (I think ICU logo is very plain/bland, but obvious as in spells out ICU).

Dart has this.

Most Google logos are abstract, say GCP.

JavaScript went minimalistic (after the old almost Java ripoff) here

Anyways, others are free to contribute ideas.

I do have SVG files, but Git doesn't like them, except if I zip them.

If we want something like the original ICU logo, we could try simple variations. Won't win any design awards, but checks off Shane's three requirements.
