Compresses files using Huffman coding.

On The Great Gatsby in plain text on project Gutenberg, it achieves a 0.526 compression ratio when using a word size of two bytes. On an arbitrary RAW image, it peaks at .622 with a 32 bit word size and .645 with a 16 bit one.

To run with Nix:

nix run ".#" --experimental-features "nix-command flakes" -- compress < myFile > myFile.compressed
nix run ".#" --experimental-features "nix-command flakes" -- decompress < myFile.compressed > myFile-decompressed
sha256sum myFile myFile-decompressed
wc -c myFile.compressed myFile 

To run with cabal:

cabal run . -- compress < myFile > myFile.compressed
cabal run . -- decompress < myFile > myFile-decompressed
sha256sum myFile myFile-decompressed
wc -c myFile.compressed myFile
