Can we make writeData public instead of protected?

[T-vK]

I'm currently trying to write a class (extending from MidiCommon) that encapsulated the functionality of BLE Midi, Apple Midi and serial Midi.

The easiest way (in terms of sending) would have been to do sth. like this:

void MultiMidi::writeData(MidiMessage *msg, int len){
    serialStreamOut->writeData(msg, len);
    bleServer->writeData(msg, len);
    appleServer->writeData(msg, len);
}

But unfortunately AppleMidiServer::writeData and MidiStreamOut have writeData set up as a protected method meaning I can't call them as shown above.
For MidiBleServer::writeData, surprisingly it is not protected. But still, for the other classes it creates great inconveniences for my use case.

It would be nice if we could simply make that method public consistently. Sort of like the internal Print class has write set up publicly.

I would be willing to create a PR for this.

Fine with me: How about adding a new public write() method to MidiCommon which calls writeData

Sure, that would work for me too!
