Suggestion: support iPod USB protocol

[PDXsailor]

Since I see no mention of it I assume that your project is intended to output to headphones only. A lot of cars were made to interface to iPods as a music source, prior to Android Auto and Apple Carplay. My iPod just died so if I want to continue using an iPod in the car I will need to buy a used one. It would be pretty cool if your device could fill that role. I am not aware of any FOSS project that outputs in the iPod format but perhaps one exists. If not then reverse engineering it might be a bit much...

I am open to someone creating a branch to work on this. I have no Apple devices, so am unable to develop (and test) an implementation of the suggested feature.
