Use external 32.728kHz crystal (RCC_LSE) for RTC #115

Optionally make it compatible with the original firmware in case the OFW is used. Could perhaps look for a magic value in RAM and not re-initialize the RTC or something like that.

This has been implemented in the STM32 RTC patchset that was merged to 'main. The patchset does not reset time, so I would assume that if time is set in the OFW it will remain the same in the retro-go as well.
