fix: reapplying conditions no longer removes them

[SondreElg]

Add functions addCondition and removeCondition to creature.ts to allow for better handling of conditions. Add remove_status field to CreatureUpdate, which is used to call creature.removeCondition. Add remove_status to logger.types.ts and move logging of condition removal to the logger

Pull Request Description

Change behaviour upon reapplying a condition to not change the state of the tracker if the conditions are considered equal.
Note that comparisons on IDs is specifically not done in order to avoid problems with improvised conditions.

Changes Proposed

• Reapplying a condition no longer removes it from a creature
• Handle adding and removing conditions as separate operations
• Move logic for logging removing conditions to the logger
