feat(www): Allow to use physical keyboard as hid input
Import a pretty printed version of keysight.js from https://github.com/fresheneesz/keysight/blob/master/dist/keysight.umd.js and use it to catch the keyboard input in the web interface. Adjust the keyboard mappings accordingly allow virtual and physical keyboard input to be forwarded to the hid input at the same time. Signed-off-by: Tobias Schaffner <[email protected]>
