Possibly unnecessary install dependency `appdirs`

[samueldg]

The current version of this library on master requires installing the appdirs library:

analytics-python/setup.py

Line 29 in ea368ae

"appdirs"

If I'm not mistaken, this only seems to be used for CI:

analytics-python/.circleci/config.yml

Line 27 in ea368ae

- run: pip3 install --user appdirs

which also installs it explicitly. I don't see any other reference to appdirs in the actual code.

Perhaps this should be moved to a separate dev-requirements.txt or something which is installed during CI and by devs?

Looking into this, I do believe you are correct. Change coming soon
