nflseedR 1.1.0

• Added the data frame game_summary to the output of simulate_nfl() which aggregates matchups across all simulated seasons (#24)
• Updated the description of some variables in load_sharpe_games() (#24)
• The output of simulate_nfl() is now of class nflseedR_simulation which allows the implementation of a summary() method that computes a gt() table of the simulation summary data frame. (#26)
• The standings data frame calculated by compute_division_ranks() now outputs losses and ties as well. (#27)
