Driver for Microinfinity CruizCore XG1300L

Tested and working.

The only drawback is that it has to be called manually (doesn't follow LEGO recommendations)

I will try to locate some other information in i2cdump that could help identify it.

RESET was also implemented as a mode - it changes scaling factor for accelerometer back to 2G.
This was undocummented by the manufacturer.
the extra information in the values here would be better as footnotes, otherwise the table in the automatically generated documentation will be wider than the screen.
