Update SPI error display and handling
For easier identification of a communication problem the RX state of Main and RTE is displayed in the debug view.
Also error reactions are now handles based on this state. E.g. RTE resets its DMA incase Main reports a data shift which can not be resolved by Main itself
In addition the timeout for error detection has been decreased to have a faster reaction
