[FEATURE] Implementation of FastAPI Framework

[SRP457]

Describe the Issue
The current model makes use of the Flask web framework for implementing the model. Now with the existence of many more robust frameworks, implementing one such frame work that is FastAPI would be beneficial.

Solution
Create a FastAPI implementation of the existing Flask model that has basic functionalities provided by it. Any extra features that seem appropriate or aesthetically pleasing are well appreciated.

Test
Ensure the model makes use of the existing python scripts and matches to form teams and display them accordingly.
i.e. It should be seamless to integrate with the current scripts and project.
