Fix HrPw array offset SEGV

On very short rides the array bounds checking in HrPwPlot
and HrPwWindow was missing. This meant that attempts to
find delays or apply delays that were longer than the
ridefile itself generated negative array offsets, and thus
a SEGV.
Added very short (12s) test ride

.. to check bounds checking in array processing
.. especially in the histogram/HrPw charts and metrics
