• Update to latest changes from micropython#16057, which fixes Thing Plus RP2350 from hanging in some situations (eg. trying to toggle WL_GPIOn before activating WLAN).
  • PR had some force pushes that deleted commits, made new branch rather than trying to manually fix
• Enable split heap on Thing Plus and Pro Micro RP2350 to use all available RAM
• Increase GC stack size on Thing Plus and Pro Micro RP2350 to avoid long collection times (see micropython#15620 (comment))
