This PR completely removes `task.c / task.h` from `sw/controller` STM32 code. Additionally, these changes were implemented: - Updated IPL3 - Added new diagnostic data (voltage and temperature) readout commands for USB and N64 - Fixed some issues with FlashRAM save type - Joybus timings were relaxed to accommodate communication with unsynchronized master controller (like _Datel Game Killer_, thanks @RWeick) - N64 embedded test program now waits for release of button press to proceed - Fixed issue where, in rare circumstances, I2C peripheral in STM32 would get locked-up on power-up - LED blinking behavior on SD card access was changed - LED blink duration on save writeback has been extended - Minor fixes through the entire of hardware abstraction layer for STM32 code - Primer now correctly detects issues with I2C bus during first time programming - `primer.py` script gives more meaningful error messages - Fixed bug where RTC time was always written on N64FlashcartMenu boot - sc64deployer now displays "Diagnostic data" instead of "MCU stack usage"
