fix: dependency conflict resolution. for a clean start of installatio…

[jhonvidal]

Correct and clean the dependencies file for proper functioning.

Description

Clean the Pipfile file for correct operation. This also solves many conflicts for people who want to start installing the demo.

Indirectly corrects the incidents: #41 and #43

Rationale

After many years, some dependencies were updated and created conflict with this project.

During hours of line-by-line testing, I managed to correct the Pipfile so that new people could test the project stably.

Little by little I will study the code and manage to improve and above all update this project.

I recommend using python version 3.8.x for the moment.
