4eaa0b3353 [SC64][FW] Flash: fixed partial page write + handle data mask during write
Flash memory module had an issue when ending address was not page (256 bytes) aligned.

Now it's possible to write single bytes to the Flash instead of being forced to do 16 bit aligned writes.

[SC64][FW][SW] Controller rewrite to remove task subsystem + minor bug fixes (#64)
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"
