predictive target weight. Added skip long tasks for one cycle if brew has finished and block display if near brew finish. Added MQTT entry for flow rate

removed full screen display changes, flow rate is still visible through mqtt at 5s intervals and 500ms intervals during brew |

Using the scales it calculates the flow rate using least squares, a method used to determine the trend line of a set of data.
Using the flow rate it stops the brew early to end with a weight closer to the desired target. The amount that trickles out varies with different flow rates, so this should get closer than a static offset.
A check for kBrewFinished was added skip long tasks for one cycle if brew has finished, improving performance.
