feat: added progress indicator at the start of create

[chiragbhatia8]

Description

This PR adds a progress indicator to the eksup CLI tool to provide users with a
better understanding of the progress of the analyze and create operations. We are
using the indicatif crate to implement the progress indicator. Here is a summary of
the changes and considerations:

A new ProgressTracker struct is implemented in a separate progress.rs module. This
struct handles creating and updating the progress bar based on the percentage of
progress made.

The progress tracker is initialized at the beginning of the analyze and create
functions. It is updated at significant milestones within the functions using the
set_progress() method.

The progress bar relies on an approximate progress percentage rather than a fixed
number of tasks. This approach allows for greater flexibility, but may be less
precise than having a predetermined number of tasks. Be sure to adjust the progress
updates in the code based on a good understanding of the overall process.
