`StreamExt::find` method analogous to `Iterator::find`? #2705

This is something I've always wanted in Stream-based code. Right now I have to use manual while-loop iteration for anything involving "read from this stream until something you need is found, then stop". The "stop" part also makes it impossible to express with fold and the like.

Is there any update for this?
