fixes issue with SDCard driver and also changes how themachine.SPI.Bus driver works
The spi bus driver has now been split into 4 different buy types.* `SPI.Bus`: normal SPI bus type* `SPI.DualBus`: Half duplex using both the miso and mosi pins for transmitting or receiving. This makes the driver 2 times faster when sending a ot of data* `SPI.QuadBus`: Half duplex using a total of 4 pins/lanes to transmit and receive* `SPI.OctalBus`: Half duplex using a total of 8 pins/lanes to transmit and receive
