Prepare a package for publishing

[anton-ptashnik]

This PR intends to assist with publishing the package to PyPI by:

• making some changes to package metadata
• adding a GitHub action for publishing a package easily from GitHub
• providing steps needed to publish a package
• address Feature request: publish the package to PyPI #5

Initial setup to allow package publishing

1. Login to https://pypi.org/ (create an account if missing)
2. Generate a token
   2.1. Go to Account Settings -> API tokens
   2.2. Create a new token. Name - any, Scope - entire account
3. Put the token into GitHub secrets for the repo
   3.1. Go to the repo settings -> Secret and Variables
   3.2. Create a new secret with name=PYPI_TOKEN and value=generated token

Steps to publish a package

Note these steps need to be done after the PR is merged so release is done on this original repo rather than on the fork.

1. Go to Releases of the repo
2. Create a new release:
   2.1. Create a new version tag, v0.1.0 for the first release
   2.2. Press Generate release notes. It makes release name == tag name and puts a default description
   2.3. Optional. Modify the description to explain changes better if needed
   2.4. Submit

Once done, GitHub starts a publish action and the package will appear on PyPI in a few seconds

@Geek5510 please update/extend authors list as needed. I recognize my work was based on knowledge of others about device API

[anton-ptashnik]

@Geek5510 I'm not strong in licensing but I'm almost sure a published package should have a correct one. I see the repo has some custom license while open source projects usually have MIT or similar one.
Please review if the current license still fits and make changes if needed

Thank you for your suggestions and work! we'll check about the licensing and see what can we do
