## HAL
- SPI: Cache the SPI device in the communication interface. Architecturally, this makes a
lot more sense because each ComIF should be responsible for one SPI bus.
- SPI: Move the empty transfer to update the line polarity to separate function. This means
it is not automatically called when calling the setter function for SPI speed and mode.
The user should call this function after locking the CS mutex if multiple SPI devices with
differing speeds and modes are attached to one bus.
- SPI: Getter functions for SPI speed and mode.
- I2C: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1.
