Changed 1) fixed the statsbomb module so the event dataset has simplified names for the end coordinates. Previously they were shot_end_x, pass_end_x etc. Now they are under three columns: end_x, end_y, end_z.
0.0.10
-----------------------
Fixed 1) fixed the statsbomb module so it works when the json is empty.
