Show HN: Stream live open data in two commands

Hypermass CLI is a command-line tool that allows users to subscribe to and automatically download live data streams to their local machine in real time. Users can install it, subscribe to available data streams (such as solar images from NASA), and sync the data to a folder that updates automatically as new files are published. The tool tracks which files have been processed and maintains the stream's state, allowing users to work with the data locally and replay streams if needed.
