Add MOD and MND fields to cylindermodel

Browse source 
Adds fields to the planner cylinder model for maximum operating depth (MOD)
for a bottom mix gas, and maximum narcotic depth (MND). Fields are read/write,
so changing MOD changes %O2 and vice-versa. Changing MND changes %He and
vice-versa.

When setting MOD directly, the %O2 is truncated (rounded down) to an integer,
which re-calculates the MOD, which is sometimes a few metres greater than the
input depth. This is desireable behaviour, as the rounding is conservative.
