true d5cbabf830 Add STM32CubeIDE patches
Patches to allow programming and debugging using a JLINK within the STM32CubeIDE environment.

Also firmware to turn STM32F103 into JLink-OB. However you will need to click on "No" every time you launch.

From memory, these are the pins used:
PA5 SWDCK
PA4 SWDIO
PA2 !RST (unneeded)

You may need to attach a 100ohm resistor from PA7 to PA4 for this to work.

true a47cfa7fa5 Initial bootloader implementation
Took a publicly available XMODEM bootloader and made it work on HK32F.

Known issues:
- Erase is super slow on this MCU. The upload routine erases all flash before loading, which means the first packet seems to hang. This also erases possibly persistent data stored in unused pages on flash.
