Data Patch Pipeline and Patch 001

[jikaczmarski]

This pull request incorporates a data patching methodology and a restructuring of the data folder. It also removes unused files and reorganizes things.

The web book builds great on my local machine and all figures and numbers work as expected.

In this PR is a data patch as well data/patches/patch_001 that adds the missing Southcentral Power Project data from 2013-2020.

What is the relationship between data/main.R and scripts/main.R?

What is the relationship between data/main.R and scripts/main.R?

data/main.R is a modern implementation of scripts/main.R. If we can confirm that the scripts directory has no dependencies, we might consider removing it.

[eldobbins]

OK. I don't think that needs to stand in the way of this PR. I will make an issue to clarify this in the future.
And thinking about it, it may make more sense to have the patches scripts in scripts/ but since the names of main.R conflict, that won't be possible until scripts/ is cleaned up.

(The justification for separating scripts and data is that scripts can be tracked in GitHub, but data really shouldn't. If they are separate, then data/ can be listed in .gitignore while scripts/ is tracked normally. Not really an issue with our tiny dataset - thinking of the future.)

#70

@ianalexmac this PR is OK with me (with the addition of the new issue) but I'm leaving approval to you because you are more familiar with the workflow.

[jikaczmarski]

@ianalexmac @eldobbins actually, the inline functions used to generate statistics are kept in scripts/inline_functions so there may be a case to maintain that or move it as well. Something to note, and I'll also add this note to the issue.

Great work Jesse! Thank you.
