Ability to specify I2C pins in .begin()

[NCPlyn]

Would be nice if we could specify what pins should I2C use, so I came up with this.
If anybody knows better way, please show.

just place a Wire.begin(SDA, SCL) before the myIMU begin(); and it should work.

Should look like this:
#define SDA2 5
#define SCL2 6

Wire.begin(SDA2,SCL2);
myIMU.begin();
