Still missing icons

There are still some icons missing. I am using the font and I would be very! gratefull, if you could fix it. In the CDN-Version

arrow-down-circle arrow-up-circle arrow-left-circle arrow-right-circle

are not available.

And the wrench, which is called "tool" here https://feathericons.com/ is not part of the webfont at all.

Thank you!!!
