Added Basic Layout and Using tview package for TUI

Decided to Go with tview package for building TUIs and
just added the basic layout of the app.
The Idea is to have a side menu to navigate between the other options.
Just like spotify-tui ( Which has taken inspiration from the orignal
spotify Client) and Having a progress bar at bottom ( Still figuring out
how to implement this )
