Teensy 4.0 Compile Error

Doesn't like SoftwareSerial.h, see below. It compiles fine if I remove the SoftwareSerial include on line 23 of TMCStepper.h.

I couldn't reproduce this with Arduino IDE and the Teensyduino add on. It also sounds like the errors aren't coming from the TMCStepper library.

OK, thanks for checking it out. Guess it must be related to PlatformIO somehow so will just stick with commenting out soft serial include for now.
