Multiple Great Depths Worm (worm_boss) can spawn in a wave

From my understanding, it is intended that only 1 worm_boss would spawn in an upgraded wave.

-- scripts/prefabs/cave.lua - line 303
wave_pre_upgraded = "used"   -- We've got one for the wave now, clear this so there aren't more.

However, in hounded.lua , the HandleSpawnInfoRec function does not update the component's _wave_pre_upgraded variable after a successful spawn.

-- scripts/components/hounded.lua - lines 917-924
if local_wave_pre_upgraded == "used" then
	for key, data in pairs(_delayedplayerspawninfo) do
		data._wave_pre_upgraded = nil
	end
		or key, data in pairs(_missingplayerspawninfo) do
		data._wave_pre_upgraded = nil
	end					
end

-- scripts/components/hounded.lua - lines 1037-1039
for i, spawninforec in ipairs(_spawninfo) do
	HandleSpawnInfoRec(dt, i, spawninforec, groupsdone)
end

If players are scattered into multiple spawn groups, the OnUpdate loop calls HandleSpawnInfoRec for each group. Since the flag doesn't get cleared and it remains "available" for subsequent groups, every group triggers ShouldUpgrade, resulting in multiple worm bosses spawning (have seen 3 and even 4).

Steps to Reproduce

Have multiple players scattered around the caves when an upgraded worm wave is about to happen (worm boss).
