added support to specify output path of wordlist

[Toluhunter]

Reason For Pull Request

This pull request addresses the need for a more convenient and flexible directory structure for generated wordlists in pentest assessments and CTF write-ups. The proposed changes enable users to easily specify the desired location for storing the wordlist, offering several benefits:

• Seamless chaining of commands with output stored in different directories without requiring directory changes.
• Compatibility with repositories like blackarch, where cupp is installed in /usr/share/. This avoids permission issues when writing the wordlist to the file system.

Changes Made

The following modifications have been made to enhance the functionality of the program:

• Updated the CHANGELOG.md file to adhere to proper markdown styling.
• Introduced a new -o flag to the program, allowing users to specify the output directory for the wordlist.
• Adjusted the test_cupp script to incorporate the newly added wordlist output directory feature.

@Toluhunter Hi, it seems like they don't update the repo anymore. I started with some refactoring, cleaning and bug fixing on my own fork. If you are interested in keeping this project alive, too, you'll find the repo here: https://github.com/AndreasInfo/cupp2.
