Okay,
the thing is that @PeterKietzmann and I settled on implementing just the transmitting part for now. But if the consensus is that the receiving part should be implemented to for the first PR, then this should be possible too. There the test requires a logic analyzer.

The clock speed part I also had implemented at the beginning and discarded in the end, because it didn't perform well. Most SPI slaved can handle up to a couple MHz, which won't be exceeded by using the high level pin operations with no wait function in between.
