adding advanced features of Q4 in m2

Hello Team, These are the required features to add for Q4 in milestone-2 document.

There were already existing features such as:

[x] Game period: (period: at which period of the game the event was recorded in)
[x] Shot distance: (distance_from_net: distance between the shot and the net)
[x] Shot angle: (angle: the angle with respect to the net where the shot happened)
[x] Shot type: (type and secondary_type: shot main and secondary types)
[x] Empty net: (is_empty_net: a binary variable whether the net was empty or not)
[x] Coordinates of the last event (coordinate_x, coordinate_y, are the separate columns for the x and y coordinates respectively)

And what has been done in this PR:

[x] Game seconds: (game_sec: Total number of seconds elapsed in the game) 'time' columns is actually 'periodTime'

Information from the immediately preceding event as four new features:

[x] Last event type: (prev_event_type: the type of the preceding event)
[x] Time from the last event (seconds): (prev_event_time_diff: the difference between current event and the preceding event in seconds)
[x] Distance from the last event: (distance_from_prev_event: the distance between current event and the preceding one)

Features to quantify a few more interesting things about the state of the play. Create the following three features:

[x] Rebound (bool): (is_rebound: a binary column that is true if the current and preceding events were shots, otherwise false)
[x] Change in shot angle (rebound_angle: only included if the shot is a rebound, otherwise 0. It is the angle between both shots).
[x] “Speed”: (speed: defined as the distance from the previous event, divided by the time since the previous event)

What is still needs to be done:

[x] Improve tidy_data.py script running time
[ ] Add the bonus features
[ ] Save a dataframe of the game ID “2017021065” (Winnipeg vs Washington game on March 12, 2018) in Comet.ml
[ ] Add a events_df.head() and the previous description of the added columns to the blog post
