Title: Code for iwdg module STM32F series

Added basic set of functions for the STM32F iwdg.c including update to iwdg.h to add prototypes. This is for all the F series although the F1 series has a slightly higher typical clock rate than the others. However the potential LSI clock rate variability is comparatively large so there is no point being overly precise. Tested successfully with an STM32F103RET6. Note that very short time periods <1ms are excluded for simplicity on the assumption they will not be needed.
