paralyze calculator

local function Paralyze(unitID, frameCount)
    local health, maxHealth, paralyzeDamage = Spring.GetUnitHealth(unitID)
    local second = math.abs(frameCount*(1/30)) --because each frame took 1/30 second
    second = second-1-1/16 --because at 0% it took 1 second to recover, and paralyze is in slow update (1/16)
    --Note: ZK use
    --paralyzeAtMaxHealth=true, and
    --unitParalysisDeclineScale=40
    local paralyze = maxHealth+maxHealth*second/40 --a full health of paralyzepoints represent 1 second of paralyze, additional health/40 paralyzepoints represent +1 second of paralyze. Reference: modrules.lua, Unit.cpp(spring).
    Spring.SetUnitHealth(unitID, { paralyze = paralyze })
