Preprocess Location + Basic Variables

[isanjeevsingh]

In this issue, we plan to preprocess the following variables:

'ID', 'Severity', 'Start_Time', 'End_Time', 'Distance(mi)', 'Description', 'Start_Lat', 'Start_Lng', 'End_Lat', 'End_Lng', 'Number', 'Street', 'Side', 'City', 'County', 'State', 'Zipcode', 'Country', 'Timezone', 'Airport_Code'

The goal is to impute the missing values and to drop the irrelevant columns.
