Use-Cases and Demonstrations

## Description

Integrate marsh with other tools and create the following demos:

- [x] Coordinating the build process with [PyInstaller](https://pyinstaller.org/en/stable/).
- [ ] Image building workflow with Docker.
- [x] Using the DAG features to orchestrate web scraping with Requests, Scrapy, Selenium, and/or Beautiful Soup.
- [ ] Integrate with [river](https://riverml.xyz/latest/) and sklearn for building online machine learning pipelines.
- [ ] Building concurrent workflow for backtesting trading strategies with PyBroker/Vectorbt/Backtesting.py and YFinance.
- [ ] Using marsh (with `RemoteCommandExecutor`) as a lightweight analogue to Ansible for remote systems administration.
- [ ] Integrate with Kubernetes and Nomad for Ephemeral Container Workloads.

These use-cases will, hopefully, present opportunities to find limitations, improvements, and feature ideas for marsh.
