HAL library 09- GENERAL for STM32Fxxx

With this name I mean that in this library, a lot of different stuff, maybe unrelated between, but very useful things will be implemented.

It allows you to make software reset, get reset source, disable or enable global interrupts (NVIC) and more.

It will be updated frequently but for now it’s just a start to use it in your projects.
