Two devices with the same address on different I2C buses #13

Description

Normally it would be possible to connect two I2C devices with the same address to two different I2C buses, one device per bus, and everything would function correctly. However, with io-plugins this doesn't appear to be possible. When i2cConfig is called the appropriate address and bus for a device are passed as arguments. However, when methods like i2cRead are later called, they are only passed the address as an argument and can't determine which device to address as there are two of them with the same address.

I don't actually have an issue with this but assuming it's true it seams like important information.
