Emonlib conflicts with other analogRead values.

I've a scenario where I'm using I2C interrupt and Emonlib together. I2C ISR contains several `analogReads` and emonlib measurement is running in `loop()`. I've observed that values from other `analogReads`...

I understood that precision is issue as CT produces very small voltages. Most of arduinos have ability to set ADC to use 1.1V internal reference instead of 5V internal reference....
