Audiorate has rounding errors which lead to 'clicking' in outputted sound.

A simple audiotestsrc ! audiorate ! alsasink is enough to show that.

A solution to this problem is to:
1/ convert the expected offset into time
2/ calculate the difference between the incoming buffer and the expected time
3/ convert that difference to offset
4/ use the offset difference for all further calculation

This hides the rounding errors.
