Can not install `django-phonenumber-field` properly with `pipenv`

Original issue: https://github.com/pypa/pipenv/issues/1322

When installing django-phonenumber-field strange issue happens. When running direct pipenv install django-phonenumber-field everything works fine. But when another developer tries to install the requirements from Pipfile, for some reason package phonenumberslite is missing.

I feel like this line in setup.py is the cause of this issue: https://github.com/stefanfoulis/django-phonenumber-field/blob/master/setup.py#L8

Here are the Pipfile and Pipfile.lock:

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"


[packages]

django-phonenumber-field = "*"

Describe your environment

1. OS Type: macos
2. Python version: 3.6.4
3. Pipenv version: 9.0.1

Expected result

I expect that django-phonenumber-field and all its dependencies will be installed.

Actual result

phonenumberslite is not installed.

Steps to replicate

1. pipenv install django-phonenumber-field
2. pipenv run pip freeze, you will see something like:

Babel==2.5.3
Django==2.0.1
django-phonenumber-field==2.0.0
phonenumberslite==8.8.9
pytz==2017.3

1. pipenv --rm (we simulate a situation when we have to use Pipfile for installing dependencies)
2. pipenv install
3. pipenv run pip freeze, you will see something like this:

Babel==2.5.3
Django==2.0.1
django-phonenumber-field==2.0.0
pytz==2017.3

[stefanfoulis]

Probably #211 fixes this issue. But I suspect that will upset people who want to use the lite version of the library. So maybe we should just remove the dependency and document the dependency and let the developer choose (like @WhyNotHugo suggested).

[alex-oleshkevich]

@oza4h07 , pipenv installs phonenumbers only if it in root deps. pipenv install django-phonenumber-field does not include it.
