Flask-RQ2 depends on setuptools but setuptools is not listed as a requirement

[DataKinds]

Steps to reproduce

1. Create a clean venv. python3 -m venv env.

2. Install Flask-RQ2 from source using pip install -e .

3. Trying to run/import Flask-RQ2 causes the following error:

Traceback (most recent call last):
  File "__init__.py", line 11, in <module>
    from pkg_resources import get_distribution, DistributionNotFound
ModuleNotFoundError: No module named 'pkg_resources'

I would fix this myself but I am absolutely not an expert with setuptools and I don't know where exactly to put this requirement in setup.py. Thanks!
