Include f3 package

[ki9us]

f3, Fight Flash Fraud is a utility to quickly verify that drives aren't fake. These fake capacity-reporting drives are becoming prolific online so I run f3probe on drives as part of my diagnostic routine.

I don't know any diagnostic boot disks that come with f3 so usually I boot into grml and run sudo apt update; sudo apt install f3. This requires internet of course so it'd be handy if f3 was included in grml. It's already in the apt repos and I don't think it's very big.

@ki9us this is a great idea, added it to the software list of grml-full, so the daily ISOs as of tomorrow as well as upcoming stable releases should include it, thx!
