[Feature]: Huffman Coding File Compression Tool

[Satvik-Singh192]

So, what is it about?

📌 Description

Add a new C++ project that implements a Huffman Coding–based file compression tool.
This tool should allow users to compress and decompress text files using Huffman coding, demonstrating practical data compression using binary trees and prefix codes.

---

✅ Expected Features

• Build frequency table from input file
• Construct Huffman Tree
• Generate prefix codes for characters
• Compress input file into encoded binary format
• Decompress encoded file back to original text
• Display compression ratio
• Command-line usage such as:
  • compress input.txt output.huff
  • decompress output.huff restored.txt

---

✅ Acceptance Criteria

• Correct implementation of Huffman Coding
• Lossless compression and accurate decompression
• Works with standard .txt files
