Add Cairo Graphics icon

[s-kond]

To create the svg-icon, I used inkscape and a svg-file from the github-repository that was linked in the issue:
https://github.com/freedesktop/cairo/blob/44f808fce9f437e14f2b0ef4e1583def8ab578ae/doc/tutorial/slides/cairo-title.svg

There were two primary colors:
- the blue background ("#162284")
- and the yellow/orange scarabaeus ("#f39914")

I picked the yellow/orange "#f39914", because the blue color is just used for the background - but I wasn't sure about that.

Hi @s-kond,

thanks for the contribution! Could you check the lint error so I can review your PR? Thanks.

Hi @dirien,
I checked the lint error and it shows me this:

Data file is formatted incorrectly:
   {
       "icons": [
@@ 12469 more lines
       ]
   }
+
ERROR: "our-lint" exited with 1.

So there should be a formatting error, but I don't know what's wrong or how I can solve this... Can you help me?

Maybe and Windows / Linux CR/LF issue?

Simply adding a new line at the end solved the problem, thx!
But it seems I have to change some more things - I'm working on that

HI @s-kond,

I see some little differences

Maybe try up the precision to 5?

Hi @s-kond,

Thanks for your contribution to simple-icons!

I think it's a very close fit!
