Test with additional CircuitPython platforms

[fivesixzero]

Test the HX711 driver with a variety of CircuitPython platforms.

Platforms/boards to test:

• atmel-samd, M0
  • [x] QT Py M0 Haxpress
  • [x] Trinket M0
• atmel-samd, M4
  • [x] Feather M4 Express
  • [x] ItsyBitsy M4 Express
• espressif ESP32-S2
  • [x] QT Py ESP32-S2
  • [x] Feather TFT ESP32-S2
• espressif ESP32-S3
  • [x] Feather ESP32-S3 No PSRAM
• nrf
  • [x] Feather Bluefruit Sense
  • [x] Clue
• raspberrypi RP2040
  • [x] Feather RP2040
• stm
  • [x] Feather STM32F405

Additional platforms to consider testing:

• broadcom Pi 4, Pi Zero, Pi Zero 2
  • Support for the platform is minimal since it's still in early development
• cxd56 Sony Spresense
  • Don't have one of these on hand yet
• espressif ESP32-C3
  • This chip is a bit weird to work with since it doesn't do USB mass storage but its worth testing out if time permits
• mimxrt10xx Teensy 4.0 or 4.1
  • Don't have one of these on hand yet

nrf, Feather Bluefruit Sense:

Very weird, unpredictable readings from GPIO read_raw(). Needs more investigation.

Testing is complete, with the only anomaly found being with the nrf port. That'll be investigated in #2.
