Devbugfix Sample time resolution for longer dives: If a dive is longer than the provided replay buffer then the sample data is compressed. This compression was not considered in the previous version. As result the dive was replayed with double speed because a single sample were interpretated as 2 seconds instead of e.g. 4 seconds for a compressed sample. The comprassion rate is now considered in the simulator replay function

User program conditions
The user application to be loaded into the Flash memory using IAP should be built with
these configuration settings:
1. Set the program load address at 0x08003000, using your toolchain linker file
2. Relocate the vector table at address 0x08003000, using the
"NVIC_SetVectorTable"function or the VECT_TAB_OFFSET definition inside the
"system_stm32f10x.c"

can be found here system_stm32f4xx.c
