Could you please add a LICENSE file?

Some downstream consumers of this library would like to know the specific licensing terms involved; adding an explicit LICENSE file to indicate the license would be immensely useful. Thanks in advance.

Alert is never triggered

I am using this library with the Sparkfun LiPo Fuel Gauge (https://www.sparkfun.com/products/10617) and am able to read all the different values through its interface.

I am not, however, able to get the alert interrupt working. The interrupt is never triggered and, although the measured voltage is below 3.7v and the alert threshold is set to 0 (32%) with a measured SoC of ~8, the alert interrupt is triggered and the inAlert() function always returns false.

I am currently measuring the following values with a single cell LiPo battery connected:
vCell: 3.69v
SoC: 8.58%
AlertThreshold: 32%

I2C address 0x32 Fuel Gauge

How to get Vsoc at i2c address 0x32

Calculation of Voltage wrong

Calculation of the cell voltage is wrong. Change float MAX17043::getVCell() in MAX17043.cpp:

from

return map(value, 0x000, 0xFFF, 0, 50000) / 10000.0;
//return value * 0.00125;

to

//return map(value, 0x000, 0xFFF, 0, 50000) / 10000.0;
return value * 0.00125;

This results in the correct values (verified with multimeter).
