Adding a SoftSerial port to Dual-Midi-Interface example

[Petrus125]

Just working on addition of a Soft Serial port to this Sketch using MIDI Pipes example.
Here we have merged USB+SoftSerialPort+Buttons >> Din Out.

• Bridges the USB MIDI interface to a Serial MIDI interface, and loops back
• anything it receives on the USB interface.
• You can also use the MIDI pipes to route the input and output of Control
• Surface itself, not just the input and output of MIDI interfaces. This is
• demonstrated in the @ref Dual-MIDI-Interface.ino example.
• @boards AVR USB, Due, Nano 33 IoT, Nano 33 BLE, Teensy 3.x, ESP32
• Plus addition option for a SoftSerial port. Tested for Leonardo and ProMicro 32U4
