- Re-ordered some functions of the core controller in the initialize function.
- Rad sensor is now only polled every 30 minutes instead of every device cycle to reduce wear of
the RADFET electronics.
- The SD cards will still be switched OFF on a reboot, but this is done in a non-blocking manner
now with a timeout of 10 seconds where the reboot will be performed n any case.

## Fixed
- General bugs in the SD card state machine. This might fix some other known bugs for certain
combinations of switching ON and OFF SD cards and also makes the whole state machine a lot more
robust against hanging up.
- SUS dummy handler went to `MODE_NORMAL` for ON commands.
- PL PCDU dummy went to `MODE_NORMAL` for ON commands.
