Create python-package.yml

@abhijeetmanhas this addresses #13, please have a look.

seems like we need to add doctest rst as a dev dependency, that's why tests are failing.

Hmm, looks like we need to fix some linting warnings like
./exohunter/__init__.py:3:1: F401 'os' imported but unused ./exohunter/preprocess.py:1:1: F401 'numpy as np' imported but unused as well.

I came across this. Looks like we have to change accordingly.

https://pypi.org/project/py-package-template/ seems a better alternative.

@gajrajgchouhan looks like we have a different way to set requirements in this project. See the code below

Exoplanet-Hunt/pyproject.toml

Lines 3 to 5 in a20b921

	requires = ["setuptools",
	"setuptools_scm",
	"wheel"]

[gajrajgchouhan]

well, I think the requirements are to be setup here in cfg

Exoplanet-Hunt/setup.cfg

Lines 30 to 32 in a20b921

	numpy
	pandas
	scikit-learn

I added the txt file because github action would read them from requirments.txt.
We will have to add any module in setup.cfg too.

Also the pyproject.toml is for installing the project which will read from setup.cfg.
