VPMB gradient of imperm: don't confuse atm and bar

Other VPM-B implementations (V-Planner, MultiDeco, Fortran code) take the
default gradient of onset of impermeability as 8.2 atm.  We use bar as the
pressure unit, and 8.2 atm = 8.30865 bar.

This has negligible effect on all of the calculated plans I've tested, resulting
in a maximum decrease of 1 minute in total dive time for ~150 m deep dives, but
we should get unit conversions correct anyway.
