Support for Teensy 4.0
Description
I am unable to compile any sketches that include <AltSoftSerial.h> against the Teensy 4.0 items I've purchased.
Steps To Reproduce Problem
I am using Arduino IDE 1.8.10 and the latest Teensy Loader 1.48. I can compile sketches (but not upload) for all the Teensy boards under the IDE Tools\Board:\Boards Manager up through Teensy 3.6. In looking at the AltSoftSerial-master\config\AlstSoftSerial_Boards.h, Teensy 2.0, Teensy++2.0 and Teensy 3.x are listed (and other makes of boards), but nothing specifically w.r.t. a Teensy 4.0.
Hardware & Software
Board Teensy 4.0 Shields / modules used None Arduino IDE version 1.8.10 Teensyduino version (if using Teensy) 1.48 Version info & package name (from Tools > Boards > Board Manager) Teensy 2.0 through Teensy 4.0 Operating system & version Windows 10 Pro Any other software or hardware? None yet
NOTE: I do have alternative AltSoftSerial installs, but they are all the current 1.4 version.
Arduino Sketch
Verbatim: --- #include <AltSoftSerial.h>
AltSoftSerial altSerial;
void setup() { Serial.begin(9600); Serial.println("AltSoftSerial Test Begin"); altSerial.begin(9600); altSerial.println("Hello World"); }
void loop() { char c;
if (Serial.available()) { c = Serial.read(); altSerial.print(c); } if (altSerial.available()) { c = altSerial.read(); Serial.print(c); } }
Errors or Incorrect Output
Arduino: 1.8.10 (Windows 10), TD: 1.48, Board: "Teensy 4.0, Serial, 600 MHz, Faster, US English"

Regards.
We've got the same problem with the recently purchased teensy 4.1 That's a big problem, since I can't use the sparkfun Tsunami device anymore!
I get the "Please define your board timer and pins" Error from AltSoftSerial_Boards.h..
I think adding a definition for teensy 4.1 here might be a first step.. But I don't how really, and I can't anticipate the consequences!
