readTimeStamped(int ireg,
int creg)
Reads and returns a contiguous set of device I2C registers, together with a best-available
timestamp of when the actual I2C read occurred.

I2cDeviceSynchSimpleYou can always just call this method without worrying at all about
read windows,
that will work, but usually it is more efficient to take some thought and care as to what set
of registers the I2C device controller is being set up to read, as adjusting that window
of registers incurs significant extra time.
If the current read window can't be used to read the requested registers, then
a new read window will automatically be created as follows. If the current read window is non
null and wholly contains the registers to read but can't be read because it is a used-up
ReadMode#ONLY_ONCE window,
a new read fresh window will be created with the same set of registers. Otherwise, a
window that exactly covers the requested set of registers will be created.
