Update Old Pro Micro Examples

- adjust the output for the hardware UART in **Blinkies.ino** file to distinguish betweeh the serial monitor
- add `Keyboard.begin()` in `setup()` for **SimpleKeyboard_HID.ino**  (this appears to work without initializing it but it was added to be consistent with Arduino's reference example)
- add `Mouse.begin()` in `setup()` to **SimpleJoystickMouse_HID.ino** (this appears to work without initializing it but it was added to be consistent with Arduino's reference example)
- include the ability to invert the mouse using the joystick depending on the orientation of the joystick
-autoformat
