Fixes #10214

Description of the problem being solved:

If you have Wither or Exposure yourself and import a party that also has these effects, then both effects are applied, even tho they are local to the enemies so only the strongest effect should be active and not both.

Technically if both entities are able to apply wither, I am now using the 15 strongest stacks, so if a party import only applies e.g. 10 wither stacks with 50% increased effect and I have configured 15 withered stacks with 0% inc effect, it will automatically use the strongest 15 stacks which would be 10 stacks of 9% wither and then 5 stacks of 6% wither.

Steps taken to verify a working solution:

• Import the PoB from below
• check eff dps mod for lightning and chaos to see only 1 effect applying.
• disable party effects -> personal lower effects will apply.
