Fantasy Football: Take the output from ff-highest-score.js and determine the payout amounts

ff-payouts.js

/*
  This script is used to determine the payout amounts for my fantasy football league.
  
  The script assumes the following payout rules:
  - Buy-in: $125
  - Highest points per week - $15 for 16 weeks
  - Highest points for entire season - $100
  - 3rd: $125
  - 2nd: $335
  - 1st: $700
  
  Instructions:
  - Log-in and navigate to your league's homepage. Make sure you are on the Championship round tab where the top place finishers are listed in order (Standings -> Playoffs -> Championship) 
  - Right-click and open Developer Tools
  - Copy/paste the script contents into the Console and press enter to load the script into the page
  - Execute the script within the Console by invoking the function: 
      getPaymentsForSeason({ highestWeeklyScoresData, usernameToTotalScoreMap });
      - highestWeeklyScoresData
        - an array of arrays (each weeks data is in an array)
        - Each week array contains the following structure: [week, name, score]
	- Ex: [[1, "Bob's Team", 10], [2, "Moon Slayers", 1]]
      - usernameToTotalScoreMap
        - a map of the following structure: username (String) to total score (Float)
	- Ex: {"Bob's Team": 100, "Moon Slayers": 200 };
   - The script will print to the Console a table with two columns: username (String), payout (Float)
