    Use linear regression to get better predicted battery times

    For hardware that has no rate data we use the differences in
charge over a time
    period to work out the effective rate. Using linear regression
this estimation
    is much more realistic.

    To do this, introduce a simple circular buffer and use an index to calculate
    the rate on each update.
