Issue with openssl in setup.py

[rickecon]

PR #25 had a commit right before it was merged that added "openssl=1.1.1", to setup.py. This was my fault that this snuck in as @SeaCelo was merging the PR, so it didn't get tested. This has two problems.

• In setup.py, pinning the package needs to have the following form with two equals signs: "openssl==1.1.1"
• Even with this specified correctly, which I have done in a new branch, the pip install of the ogzaf package through pip install -e . after creating the ogzaf-dev conda environment fails with the following message.

ERROR: Could not find a version that satisfies the requirement openssl==1.1.1 (from ogzaf) (from versions: none)
ERROR: No matching distribution found for openssl==1.1.1

When I activate the ogzaf-dev conda environment and type conda list openssl, I get the following:

# packages in environment at /Users/richardevans/opt/anaconda3/envs/ogzaf-dev:
#
# Name                    Version                   Build  Channel
openssl                   1.1.1s               h03a7124_1    conda-forge
pyopenssl                 23.0.0             pyhd8ed1ab_0    conda-forge

This should be an easy fix, but I don't know what it is right now. @SeaCelo @sarvonz

@rickecon If I remove line 30 from setup.py I can install and run the model using the new environment.

I'm running python 3.9.12. Could be that openssl 1.1.1 is not available for Python 3.10?
