Add some gas mix validation to the planner
A few basic rules for gas validation: We can't have <0%, or >100% of either O2 or He O2 + He must not be >100% Switch depth can't be <0% This places limits on user-input values Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
