Enable or disable partial block reads.
Enabling partial block reads improves performance by allowing a block
to be read over the SPI bus as several sub-blocks. Errors may occur
if the time between reads is too long since the SD card may timeout.
The SPI SS line will be held low until the entire block is read or
readEnd() is called.
Use this for applications like the Adafruit Wave Shield.
