added rookie college stats

[nicidob]

obvious not done 'well' or 'correctly' but a proof of concept nonetheless

Statistical technique in https://github.com/nicidob/bbgm/blob/master/make_rookie_sim.ipynb

EDIT: Tweaked the stats to scale players to more minutes to inflate the numbers a bit

pts : [-3306.873, -197.621, 64.759, -10.899] ,
orb : [-353.359, -177.691, -3.106, -1.09] ,
drb : [-863.618, -359.85, 8.32, -1.73] ,
ast : [-745.702, 150.681, -341.694, -3.096] ,
stl : [-375.889, 6.807, -3.388, -1.369] ,
blk : [-187.953, -59.902, 43.54, -0.708] ,
min : [0.0, -0.0, 0.0, 36.0] ,

Or maybe just to only use 'mostly starters'
