2.1 -> 3.0 upgrade surprise: stream: process.stderr change

[izelnakri]

What is the reasoning behind changing the default stream from stdout to stderr?

It took me quite sometime to figure out what broke in my tests. I understand it is a major version change but would be nice if it was in the CHANGELOG/README.

Wouldnt it be better to keep stdout as default as more people are having the same issue? #61

The default stream did not change in 2.1=>3.0: v2.1.0...v3.0.0

It has always been stderr: 3467596#diff-168726dbe96b3ce427e7fedce31bb0bcR11

The reason it's stderr is so that it will not interfere with normal output. Most other spinners use stderr too.
