Duplo Train remote control

The heavy lifting was done by https://www.printables.com/@Mav__1866170 you can find the original project here : https://www.printables.com/model/878210-remote-compatible-with-lego-duplo-train-using-esp3

Since the original software project misses a lib version dependency (https://github.com/mav00/LDTrainRemote/pull/1) and only supports predefined speeds, I also attached my changed code as a *.zip. (For me it works only with Platform IO)
