PNGME Message Encoder/Decoder in Rust

Introducing a program that enables you to encode messages into PNG files, decode messages stored in PNG files, remove messages from PNG files, and print a list of PNG chunks that can be searched for messages. With this program, you can securely store and transmit important information within a PNG image file. Whether you need to hide a message from prying eyes or store data in a compact format, this program provides an efficient and reliable solution.
