Corrupted Data on the SD card from STWINK HS Data Logger

Reducing the number of sensors enabled in the configuration file helps, as does slowing down the SD clock (i.e. increasing hsd1.Init.ClockDiv = n in STWIN_sd.c). We've also noted that the code in sd_diskio.c has the compile time build define "ENABLE_...
