Speedups

tox-faster implements these tox speedups:

Disables tox's dependency listing (the "env report")

Every single time you run tox it runs pip freeze to print out a list of all the packages installed in the testenv being run:

You don't need to see that in your terminal every time you run tox and if your venv contains a lot of packages it's quite annoying because it prints screenfulls of text. Running pip freeze also introduces a noticeable delay in the startup time of every tox command: on my machine with my venv it adds about 250ms.

tox-faster removes this so your tox output will be shorter and your tox commands will start faster:

$ tox -e lint
lint run-test-pre: PYTHONHASHSEED='3084948731'
lint run-test: commands[0] | pylint lms bin
...

tox-faster doesn't disable the env report on CI. The env report can be useful diagnostic information on CI so if an environment variable named CI is set to any value then tox-faster won't disable the env report. This also enables you to re-enable the env report locally by running CI=yes tox ....
