Add Interactive Text File Analyzer Script

[Jainil26]

Hi @king04aman! I am practicing my pure Python scripting skills and Git Pull Request workflow. I would love to contribute a command-line terminal script that analyzes a .txt file and outputs total character counts, word counts, and unique word counts.

May I please be assigned to work on this issue ?
