Release v3.2.0b6

Added

• Added support for PBIO_PYBRICKS_COMMAND_REBOOT_TO_UPDATE_MODE Pybricks
  Profile BLE command.
• Implemented Motor.load() which now measures load both during active
  conditions (run) and passive conditions (dc).

Changed

• The Pybricks Code stop button will force the program to exit even if the user
  catches the SystemExit exception (pybricks-micropython#117).
• Changed PrimeHub.display.image() to PrimeHub.display.icon() and renamed
  its kwarg from image to icon (support#409).
• Deprecated Control.load(), Control.stalled(), and Control.done()
  methods, but they will continue to exist in the firmware until further
  notice ([support#822]). New scripts are encouraged to use the (improved)
  variants available directly on Motor objects.

Removed

• Removed hub.system.reset() method.
• Disabled micropython module on Move Hub.
