Remove Unused Dependencies

[gdrosos]

Summary

This pull request proposes the removal of the unused dependencies: urllib3, cryptography, cffi, idna, chardet from the requirements.txt configuration file. It's part of an ongoing research endeavor focusing on the identification and elimination of code bloat within software projects. Your insights on this would be really valuable.

Rationale

The urllib3 package was added in 913bb40, the idna and chardet were added on bb5651e. Moreover, cryptography was added on 913bb40, while the dependnecy to cffi was included on 4ab3248.

However, upon analysis of the codebase, it was found that none of the aforementioned packages are currently being directly utilized within the project. Removing those unused dependencies will reduce the overall footprint of the application, mitigate potential security risks, and most importantly, simplify the dependency management process.

Changes

• Removed the dependencies to urllib3, cryptography, cffi, idna and chardetfrom the requirements.txt file.

Impact

• Reduced package size: The removal of this unused dependency will lead to a decrease in the overall size of the installed packages.
• Simplified dependency tree: Fewer dependencies make the project easier to maintain and can speed up installation.

Testing

All the unit tests pass (29/29)

Requirements

• Add your name to CONTRIBUTORS.md
• If this is a new feature, then please add some additional information about it to CHANGELOG.md
