Check CRCs and offsets in downloads.
Also, flush the file to disk only at the end, rather than after
each block. This should give a nice speedup. The CRC checking
slows things down a little but profiling indicates 91% of the time of
-[TFUSBController getFile:forPath:toSaveTo:beginAtOffset:withLooping:existingTime:]
is being spent in mach_msg called from doRecv, and only 2% in
-[TFDataFormat findCRC:length:].
