Updated I²C library — Feed-back + suggestion #97

I've tested the updated I²C library on an MSP430FR4133 connected to an INA226 sensor. Everything when fine.

I haven't tested the library as I²C slave yet.

A nice addition would be to allow to choose between the different speeds or modes (links to www.i2c-bus.org website).

Standard mode at 100 kb/s (default)
Fast mode at 400 kb/s
Fast mode+ at 1 Mb/s, when available

Hi, just pushed a version to the wire_update branch. If you would like to give it a try. Note: it uses the function prototypes from Arduino with e.g. Wire.setClock(400000); // set 400kb/s
