<Mouse>/delta missing from Keyboard&Mouse binding prompt entries

Since it's a pretty common input type, it should probably map to a sprite like : mousekeyboard_mouse_simple

Thanks for this - I'm pausing development on this (and my other packages) until Unity rolls back their per-install charge changes, but will get to this if/once this roll-back happens

I agree that would be nice. 👍
