feature request (add SPDIF digital output)

[Ryszard-wpl]

fantastic Radio and software. Thank you very much for this great job. Is it possible and easy to add SPDIF to radio? I just want to use your radio as RADIO TUNER for rest of my audio system. I have seen few realisation like for instance https://github.com/Edzelf/ESP32Radio-V2/tree/main but I am lamer and cannot use part of code into another project...... Thanks in advance. Ryszard
