Implement the macfe::periph::SpiMaster peripheral for stm32f4, linux, and cli peripherals. See the interface in lib/periph/spi.hpp and implement it in the lib/mcal.

See ST's RM0410 reference manual for the HAL_SPI commands.

When defining the STM32F4 implementation, your constructor will need some information about the physical pin configuration, such as the hspi handle and which chip select pin to use.

Your stm32f4 implementation will need an Init() function which, in the future, will be called in a project's bindings::Initialize() function.

This task only implements the Spi peripheral. You don't need to use it in any project yet

The SPI Master peripheral will be used for the LVBMS firmware
