                HAL I2C truly non-blocking reads.
              
          
    STM32 HAL I2C TRULY NON-BLOCKING MEMORY I/O

Makes HAL_I2C_Mem_Read_IT and HAL_I2C_Mem_Write_IT truly non-blocking.
Known issues:

needs a configured system timer to provide interrupts,
needs a modification in original HAL driver,
needs an extra helper (delay_async.c / delay_async.h).
internal delays depend on the timer tick time (default 1ms here) so smaller intervals require smaller timer period.
