Add Dev Container + add tutorial + general updates to the Element

[MilagrosMarin]

This PR incorporates DevContainers configured to run Codespaces and introduces a tutorial notebook with a comprehensive overview of the Element, without delving into specifics such as data mounting or other detailed aspects.

The proposed changes cover the following:

• Add DevContainer and docker-compose-db.yaml

  • Test Codespaces containerization on GitHub repository

• Modifying the following files/updating with the following changes, primarily to align the Element more consistently with other DataJoint Elements:

  • Function param types and docstring in src files
  • .github, license, .gitignore, contributing, workflows, code of conduct and codespell
  • setup.py and fix extras_require
  • The packaging requirements of elements in setup.py will now install directly from GitHub instead of PyPI (no longer updated)
  • README
  • Color in the flowchart images according to other Elements
  • version.py and CHANGELOG

• Add the following files:

  • Add tutorial pipeline
    • Set up of dj.config() for the tutorial / DevContainers in tutorial_pipeline.py
  • Add tutorial.ipynb
    • Validate the tutorial's functionality in both Codespaces and local environments.

Add to the previous changes: This PR introduces the inclusion of S3 data mounting in the DevContainer as well. This modification is accompanied by corresponding updates to the proposed tutorial, aiming to enhance the tutorial by aligning it with the rest of the Elements.

Thank you @MilagrosMarin. Just a few small things. I haven't gone through the notebook yet but will do so in the next round.
