Adds new logo and banner to home-assistant/brands repo

[tannisroot]

Hi, I saw that the logo and a banner for the project were added to the docs, which look awesome.
Can those be used for the custom integration as well, so that some sort of an icon appeared for it in the integrations UI?
I see that in order to achieve this, you need to PR to this repo home-assistant/brands, even if it's a custom integration, Home Assistant team will upload it to their server, and in turn Home Assistant will pick the icon up from the internet.

Yes that was the plan. You're just 1 step ahead of me 😄

I'm going through the checklist of things required in order to get listed by default on HACS and this is one of the items.
