bq34z100_rust

Provides an embedded_hal driver for the fuel gauge series bq34z100 (cannot change chemid)

Currently requires a STD env due to math functions, improvements or noSTD workarounds welcome!

Please note that this is mostly a direct port of https://github.com/xkam1x/BQ34Z100G1/blob/master/bq34z100g1.cpp and using some parts of the xemics conversion from https://github.com/Ralim/BQ34Z100/blob/master/bq34z100.cpp. As a result this is not ideomatic rust code.

It is possible to read all registers and perform the necessary calibrations. Setting up the chip is limited, the default chemid uses is ok compatible with most lipo and liion cells. It is possible to set the capacity and design energy but without an EV2400/EV2300 programmer it is not possible to change for eg. LiFePo. For most batteries it might be easier to just buy a bootleg programmer and set up all static value and start the calibrations via it. Then only use this to read the registers from a MCU to get state informations.

Please note, that the library is still very rough at the edges and pull requests are welcome to improve it :)
