simgine/bevy_enhanced_input

AI Summary: This issue describes a bug where the process of constructing bindings can panic, leading to a crash. The proposed solution is to handle this error gracefully by logging a warning and returning `Self` instead of panicking, as the situation is fully recoverable.

AI Summary: This issue proposes adding an "any" input binding feature, allowing developers to capture any user input without specifying a particular key or button. This would be useful for generic user input or for cancelling input sequences. The feature should be flexible enough to work selectively with specific input devices (e.g., a single gamepad) or globally across multiple input devices (e.g., all connected joysticks and gamepads).
