Optimization to remove redundancy in code

[samruddhibothara]

I have removed the redundancy in code optimization in get_heatmap and instead added the option to return a list of all coordinates in detect_players_video (by default, this parameter heatmap=False) So in the get_heatmap method, I first initialized the court, then called the detect_players_video method (with parameter heatmap=True) which returns all coordinates This coordinate list returned is then used to generate heatmap

I have also made slight changes in the utils.py file to create a method to get the default frame list

This is making the tqdm bar for detect_players_video and not for get_heatmap This issue might have to be solved and required code added, or since there isnt much of a time difference as get_heatmap is only drawing points from a list (max 1-2 seconds ) after rendering video, it can also be ignored
