An embedded-hal driver for the MAX1720x fuel gauge ICs
This driver is loosely based on Tock's MAX17205 driver but rewritten to use embedded-hal's I2C driver instead of the one built in to Tock's kernel. It does not take ownership of the I2C bus so works in conjunction with other I2C drivers.
Tested on a Raspberry Pi with a MAX17205 but should in theory work on any embedded-hal I2C device and with any of the MAX1720x family of ICs.
