Fix Medical HandleDamageWounds memory leak

[dedmen]

Do what title says.
compile command caches string indefinitely. Meaning every combination of wounds and pain will stay in memory forever till the game exits or crashes.

Btw while we're at it.
https://github.com/acemod/ACE3/blob/master/addons/medical/functions/fnc_handleDamage_wounds.sqf#L29 what is up with _woundID? It's never changed, but
https://github.com/acemod/ACE3/blob/master/addons/medical/functions/fnc_handleDamage_wounds.sqf#L62 set onto the unit and causing network traffic.
Actually that variable is never used. It's only initialized to 1 in medical init and then never used again..

Or is woundsOld used if extension isn't there? But why, ACE force kills the mission anyway if the extension isn't available, so that doesn't make much sense.

Ah yeah that's what's happening
https://github.com/acemod/ACE3/blob/master/addons/medical/XEH_preInit.sqf#L11
But. As I said that doesn't make much sense if ACE doesn't let you play anyway if the extension is not there. And if the extension is there we also don't need that variable.
Actually the extension uses that variable. But it's never set back to the lastUniqueWoundID variable.
And the extension itself also doesn't store that it increments the _woundID. Is this a bug?

IIRC, we've talked about dropping unique wound ids

Correct, as they would have been used only to do individually targeted treatment which I think we decided is unnecessarily detailed.

Edit: The full conversation happened in slack, but see here #6468

Makes sense, as there currently doesn't seem to be any use nor sense for it. Unless the extension isn't there, which only can happen on linux dedicated server.

Why twice?
