Add Unixstickers to the suggested vendors

[Facens]

Unixstickers has a complete hexagon stickers collection: http://www.unixstickers.com/tag/hexagon
You may want to add it as one of the vendors : )

@Facens Oh cool.

Do we know of other companies with compliant sticker collections?

[Facens]

I don't know of any others personally

https://hexbadger.com is 100% compliant with this repo & https://sticker.how/.

Disclaimer - I own the site and started it because I was disappointed at the lack of good sources for standardized hex stickers.

I'm happy to add additional designs that you'd like to see (as long as there are no licensing issues, of course).
