Split Result from Kaur

[tgautier]

Kaur has grown into something that is both very generic (mainly, Result) and that is relevent for others to use (I hope 👼) and a lot of stuff that is kind of useless outside of Fewlines.

After discussing it with @fewlinesco/team we decided to split Result from the rest of kaur.

So, we need to decide on a name (keep kaur for Result) and on what to do with Circuit.

I suggest we keep kaur for the public project with Result, just because I like kaur and circuit working together 😁
