[FEAT]: Add a command parser

[Vyvy-vi]

Feature Request

Is your feature request related to a problem? Please describe:

Code was modified to include individual commands as subclasses of the Command class.

Open main.cpp and implement the parsing logic used by the if-else statements to map the Args object to a given command based on the value in the first arg. It's alright if the -h flag breaks.

Describe the solution you'd like
