`--untracked-files` and `--unchanged` coupled with `--granular`
puts a lot of stress on `show_status`. Currently, with those options,
dvc spends ~26s on `_show_status` function.
Unhappy with the above result, I looked into improving the situation with
`console.out`. It did reduce that to 9s but it still felt like a lot.
Then I dropped to good old colorama, which dropped to 3s(term)/1.24(redirected).
I tested with buffering output which dropped this further to
~600ms(term)/~100ms(redirected).
This may seem like premature optimization, but this was preventing me
from figuring out perf issues in granular outputs, and I believe the
user should not be penalize for using feature that we already offer.
