1.10.0 - support more boards, especially w/ UF2 bootloaders; update sample.auniter.ini

• 1.10.0 (2023-06-18)
  • Add --clean flag to auniter.sh
    • tells the Arduino-CLI tool to clean its build cache.
    • Sometimes it caches too aggressively and does not detect changes to
      third party Core files.
  • Update --port {value} flag of auniter.sh
    • Allow none value to allow an ATtiny85 to be programmed
      through USBtinyISP instead of the serial port.
    • Allow glob such as /dev/ttyACM* or just ACM*.
      • Tells the script to select the first /dev/ttyACM* port that
        matches the glob.
      • Added to support the Adafruit ItsyBitsy M4 which seems to have a
        flaky UF2 bootloader such that new firmware is flashed at
        /dev/ttyACM0, but upon reboot, the device appears at
        /dev/ttyACM1, which causes lots of confusion.
  • Add --delay N flag to auniter.sh
    • Some boards, especially those using UF2 bootloaders, take too much
      time to reboot, causing the serial monitor to fail with an error
      because there is no serial port ready yet.
    • This flag allows a short delay before the serial monitor is fired up.
  • Update sample.auniter.ini
    • Update nodemcuv2 configuration to be compatible with latest
      ESP8266 core software.
    • Add additional boards, e.g. SparkFun Pro Micro, Arduino Pro Mini,
      Seeeduino XIAO M0, Adafruit ItsyBitsy M0 and M4, Teensy 3.2
  • Support only a single board in a single auniter.sh command
    • Previously allows a comma-separate list of {board}:{port} arguments
      e.g. auniter.sh test nano:USB0,esp8266:USB1,esp32:USB2 SampleTest.ino.
    • This feature was never reliable because the USB port of a
      microcontroller would be randomly changed by the host operating
      system.
    • And the workflow of compiling the firmware, flashing it, and running
      the unit tests was far too slow, and would sometimes fail for no
      apparent reason.
