Implement logging to file for the CLI

[LunaticMuch]

The CLI tool is great but it logs everything on the stdin only. While the stdin can be redirected to a file, the CLI should provide an argument like --log to dump the result into a file. This might be also taken to the extreme of providing text and html log.

I am happy to collaborate on making this, if somebody else sees a value.

• [ ] Log into text file from cli argument
• [ ] Log into html file from cli argument

We have two different things here

• log to a file (not sure why to do something different than $ graphql-inspector diff > diff.log)
• save output in different formats

I'm okay with the second thing.

Still relevant? @LunaticMuch

Actually I don't think so. I close it.
