Dbf xbrl mapping

[zaneselvans]

What this PR does

• Adds some pre-commit / git magic to ensure that all CSVs (and other text files) have Unix-style line endings in the repository, so we don't get full-file diffs whenever we edit a CSV using Excel / Libre Office.
• Applies that magic to all our existing CSVs.
• Renames some of the values & columns in the DBF to XBRL row mapping CSV to be more generic, since the nomenclature of the Plant in Service table doesn't apply across all tables we are using it to transform.
• Add a new CSV dbf_to_xbrl_tables.csv that associates old DBF tables with new XBRL tables, so we know which of them are related to each other. This will supplant the table names dictionary we have in pudl.extract.ferc1 right now, and is necessary because there are one-to-many and many-to-one relationships between these tables.
• Corrected & added details to our FERC Form 1 data dictionary table descriptions -- stuff I discovered while trying to map the DBF & XBRL tables to each other.
• Removed the old row-mapping metadata for the plant_in_service_ferc1 table, since it has been replaced by the new DBF + XBRL alignment process & mapping.

PR Checklist

Before requesting a review of your pull request, please make sure you've done the
following:

• Merge the most recent version of dev (or the appropriate upstream branch) into
  your branch and resolved any merge conflicts. You may need to do this several
  times over the course of a PR as dev changes frequently.
• Verify that all of the CI checks on your PR are passing. See
  Running Tests with Tox
  for details on how to run the full test suite locally if you need to debug a
  particular failure.
• Ensure that the docstrings for any new modules, classes, functions, or methods are
  descriptive enough for developers and users to understand your code.
• If you expanded data coverage or changed the outputs, ensure that the full
  data validation tests
  pass locally on a fresh DB.
• If you've added new functions or classes, ensure that they have at least basic
  unit tests.
• If you've added new analyses, make sure they include defensive sanity checks that
  will catch unexpected data issues.
• Update the
  release notes
  to reflect your changes. Make sure to reference the PR and any related issues.
• Do your own review of the PR. Add comments highlighting areas where you have
  questions you'd like reviewers to answer, known issues, solutions you're
  unsatisfied with, or other things that deserve special attention from the
  reviewer.

this looks mostly good. this is a future suggestion, but I think for this kind of pr it would have been helpful to have a lil list of the things you did and why bc there are a few disparate things going on in here. but generally...

• lots of csv's touched bc of the gitattributes/pre-commit changes
• more table descriptions in our ferc db data dictionaries
• renaming xbrl_column_stem to xbrl_factoid
• renaming some of the row_types in the dbf to xbrl map.
• anything else?

I have a few calrifying questions but generally this looks just fine to me.

@cmgosnell I added a description to the PR. Sorry I left that out. This is a mishmash.
