Switch to pretty_env_logger?

https://github.com/seanmonstar/pretty-env-logger is pretty. Anyone feel for or against switch to it?

👍 from me, and I would be ok fixing #6189 at the same time.

I'm personally a fan of env_logger due to how minimal it is where this isn't really an oft-used feature of Cargo that we want to pay a lot for in terms of dependencies, compile time, code size, etc. Along those lines I think I'd personally prefer to stick with env_logger today, but I don't feel too strongly!

@alexcrichton what if I feature flag it? My usecase is when debugging cargo in tree anyways 😄

Seems plausible to me!
