This release adds Control-C support at the console to reboot the microcontroller (which is used by the 'Reboot' button in the latest zeptocom.js), providing it is not severely wedged, adds optimizations for sending and receiving bytes as master over SPI, fixes a lurking bug where the incorrect use of bis! to set NVIC registers in the interrupt module was masking a significant interrupt-handling bug in multicore operation on the RP2040 by incorrectly clearing pending interrupts which would otherwise be unhandled, and fixes the aforementioned RP2040 multicore interrupt bug which was unmasked by fixing the aforementioned incorrect use of bis!.
