Bevy Enhanced Input 0.26.0

Changed

• Update to Bevy 0.19.0.
• Adjust the scaling of input values for Binding::mouse_wheel() when input comes from trackpads, so they are scaled the same as mouse wheels. In other words, MouseWheel events measured in MouseWheelUnit::Pixels now result in a similar feel as those from MouseWheelUnit::Lines, by dividing by MouseScrollUnit::SCROLL_UNIT_CONVERSION_FACTOR.
