Implement GPA score

[JuanVqz]

• [ ] Add an entry to CHANGELOG.md that links to this PR under the "main (unreleased)" heading.

Description:

I'm trying to solve #95 following the GPA (grade point average) score but the example there used the 4.0 scale and I'm not pretty sure if we want that.

Closes #95

If changes to the behavior are made, clearly describe what changes.

I will abide by the code of conduct.

Have a question, are we interested on have different types of A+, A, A- (and so on) in the report? will be useful or it is confusing?

The range that I used was found on the internet but it will be great if you can confirm that it is the correct one.

Ex. of a simplified version.

# |Letter Grade | Percent Grade | Scale |
# |:------------|:-------------:|------:|
# | A           | 0-69          | 4.0   |
# | B           | 70-79         | 3.0   |
# | C           | 80-89         | 2.0   |
# | D           | 90-96         | 1.0   |
# | E/F         | 97-INFINITY   | 0.0   |

      def score
        case @skunk_score
        when (0..69)
          "A"
        when (70..79)
          "B"
        when (80..89)
          "C"
        when (90..96)
          "D"
        when (97..Float::INFINITY)
          "E"
        end
      end

I haven't fixed the linter because we may modify the logic there.

Hey guys! Loving this idea! @etagwerker requested some real world results to work against, so here's the top 20 scores from a recent run at our place (sans the file names). We literally have hundreds of files this runs against, so if you need deeper data, let me know!

@JuanVqz I don't think we are interested in this at the moment:

I'm going to close this pr, I think we give it a shot later, thanks @etagwerker
