Add visual progress indicators

[Daru-san]

Introduction

In this pull my goal is to create visual indicators for running operations.

It is supposed to be a continuation on #1, this time focusing solely on expanding on the TaskQueue and adding visual indicators of progress.

Goals

• Add visual indication of tasks
• Abort with helpful errors showing exact stage of failure
• Sync progress with TaskQueue operations

So far, I have been considering using the TaskQueue along with the GlobalProgress struct implemented in this pr to track and display progress on current tasks.
I am not necessarily sure about how I will co-ordinate them, whether the task queue will handle both tasks and displaying progress or whether I will have to wrap that functionality in a whole other struct.

However I want to avoid too much encapsulation as to avoid the overhead of multiple different structs contained in other structs (somehow) interacting with each other.
At the same time, I do not want to make my run and run_batch functions too long, as that would become difficult to read.

Due to a realization that error handling is still incomplete, I will merge my current progress and work on error handling.
This pr has changes that I would need to flesh out and that require that I complete error handling as a proper feature.
