gpus

and then press q to quit

• ram in GBs
• Modify layout to show all GPUs with each GPU's charts on a single row
• Double the height for better visibility
• Replace random data with nvml_wrapper for real GPU usage
• Add GPU memory usage bars alongside GPU usage bars
• Fix display issues with bar rendering and add "press q to quit" text at bottom
• Implement a random number generator as the data source for the bar charts
• Render the bar charts in the terminal and update them in real time
• Limit the chart to a configurable number of bars wide (x bars)
• Start with 1 bar wide, allow dynamic resizing (e.g., with arrow keys)
• Make each bar thicker (draw multiple columns per bar)
• Refactor rendering to use a more advanced terminal control library (e.g., termion or tui-rs) for efficient, flicker-free updates
• Fix exit handling so Ctrl+C and 'q' both work reliably
• Make each bar stretch horizontally to fill the available width when its value is 100
