remove pytest-runner from setup requires

[NEGU93]

I cannot seem to find why pytest-runner package is necessary (see here).
My work proxy don't have this module and therefore it prevents me from installing upsetplot. (I tried --no-deps but fails anyway).

Is it possible to remove it?

Also, it seems deprecated. Source

Deprecation Notice
pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example ‘setup_requires’ and ‘tests_require’ bypass pip --require-hashes. See also pypa/setuptools#1684.

It is recommended that you:

Remove 'pytest-runner' from your setup_requires, preferably removing the setup_requires option.

Remove 'pytest' and any other testing requirements from tests_require, preferably removing the tests_requires option.

Select a tool to bootstrap and then run tests such as tox.
