[feature]Adding Modularity and Refactoring

[manmita]

Is your feature request related to a problem? Please describe.
The project lacks proper code structure and there is a lot of code redundancy.

Describe the solution you'd like
I would like to create a design for the code such that functions like draw() are reused which will allow users to use these functions and build up on it. Also adding a file structure will help users to navigate easily.

Proposed file structure
a) src:
--->1) main.py - which calls the 3 audio visualizers based on user input
--->2) util - containing draw.py and other utils
--->3) visualizers - which contain the main code (importing the utils required)
b) documentation
c) guidelines

Additional context
I would like to contribute these changes to the main project. Please assign me this issue @Soumya-Kushwaha
