Complete transition into using poetry and more

[ificiana]

Describe the solution you'd like

As mentioned earlier by @ronnie-llamado in #235:
The PR accompanying this issue (#288) aims to complete the process. Moreover, it explicitly adds support for Python 3.11

Tasks

To Do

• Move PyPI information (version, classifiers, etc) over to pyproject.toml
• Remove extraneous pipenv files (when the transition is complete)
• Update Makefile for versioning

Up for Discussion

• [?] Add new GitHub Actions workflow to push the package to PyPI on a new tag
  I personally prefer the CLI commands for publishing, but if needed we can update the workflow as needed.

Extras

• Add support for Python 3.11

Additional context

Testing the versioning system: Example Output

$ poetry version
pyhumps 3.8.0
$ make deploy-patch
  poetry version patch
  Bumping version from 3.8.0 to 3.8.1
  git commit -m 'Bump version: 3.8.0 → 3.8.1' pyproject.toml
  [master XXXXXXX] Bump version: 3.8.0 → 3.8.1

  Publishing pyhumps (3.8.1) to test-pypi
   - Uploading pyhumps-3.8.1-py3-none-any.whl 0%
   - Uploading pyhumps-3.8.1-py3-none-any.whl 57%
   - Uploading pyhumps-3.8.1-py3-none-any.whl 100%
   - Uploading pyhumps-3.8.1.tar.gz 0%
   - Uploading pyhumps-3.8.1.tar.gz 100%

@nficano this step needs the API key as a repo secret, we can use this workflow depending on what you're comfortable with...
