stm32g491 support? #52

My WAG and heads up, stuff like (untested, I am a few weeks away from this being a priority) is missing:

    stm32g491xe \:
            ${MAKE} bootloader FWCPU='-mcpu=cortex-m4' \
                    FWSTARTUP='mcu/stm32g4xx.S' \
                    FWDEFS='STM32G4 STM32G491xx' \
                    LDPARAMS='ROMLEN=512K RAMLEN=112K USBD_ASM_DRIVER'

But I am sure that is flawed since usb driver, albeit similar to stm32f4 from the HAL perspective, might not be from the lower level driver perspective. IDK. I have a NUCLEO-G491RE in my hands where I am working on porting an application from stm32f429 and noticed that to use sboot_stm32, it was borken. Once application port and bringup is done, then I can test sboot_stm32.

Confirmed, code is not appropriate for a Category 4 stm32g4 device :-(, the code in mcu is only for Category 2 and Category 3 devices. Attempts to flash fail during the erase phase as it tries to use the Category 3 option. Is there anything I can do to help?
