Fixed Collisions in generate_code() Method

[aharris2404]

Hello Alfredo!

Love PandasBasketball. But I noticed some bugs with the pandasbasketball.generate_code() method and thought I could contribute.

Issues with master branch:

1. If user inputs non-ascii characters such as get_player("Greivis Vásquez"), pb returns statuscode.404
2. If user inputs player with more than two names, such as get_player("James Michael McAdoo"), pb returns 'ValueError'
3. If user inputs player who shares the same first 5 letters of last name and first 2 letters of first name with another player, such as get_player("JaKarr Sampson"), pb returns DF with stats for Jamal Sampson.

My code:

• Works by finding the page listing all the players with a last name starting with the same letter the user-inputted last name and then finding the latter part of the URL for that player's stats page
• Fixes (1) as long as non-ascii characters aren't the first letter of the last name
• Fixes (2) except in cases where player's apparent middle name is actually the beginning of their last name, such as Luc Mbah a Moute
• Fixes (3) completely
• Retains the original method as a backup in case a user wants to type in ascii characters for a foreign player
• Makes a slight change to errors.StatusCode404 to let user know the source of the issue might have been a mis-typed player name

It should be a strict improvement (not introduce any bugs that weren't already present).

Thanks! Let me know what you think.
