create requirements.txt or conda env YAML based on Report

[banesullivan]

We should implement the ability to create a minimalist requirements.txt or conda environment YAML config file based on the Report

All too often, I need some sort of environment config to specify hard versions of what was used in an experiment when sharing it with others for reproducibility but exporting the entire environment is not necessary - I simply want to specify a few packages (like 10-20... so doing it manually is cumbersome) that are relevant to the project and leave it at that. I think scooby is well poised to implement this kind of feature.

With this, it might be cool to implement a command-line interface that could scrub all the Python/Jupyter notebook files in a directory for import statements and keep track of any modules that aren't in the standard lib then generate a versions report for the current environment with all of those packages

This would make creating requirements.txt or conda config files a breeze in scientific experiments

If a version is unknown, then we simply don't specify a version and throw a big ole warning at the user
