Addon: [1.7.53] - Fix: improved way to detect kills by honoring cell show time.

[Xian55]

The original idea:

• Create a construct which has a fixed update time to periodically update the cell value(COMBAT_LOG_ITERATION_FRAME_CHANGE_RATE) is currently 5 update tick. This is tied to the FPS(higher the number it happens more often)
• Make the ability to interrupt the deterministic update flow to react the change instantly meanwhile honouring the periodically update(when a kill happens, don't fully await the 5 update ticks, but rather show the value immediately, but make sure to show the value for the 5 update tick duration)
• What left out is to record the actual event time, and based on that recorded time wait for at least COMBAT_LOG_ITERATION_FRAME_CHANGE_RATE duration

The problem:

• Below certain amount of stable cell wait time - usually below 5 update tick - the system become unstable and the backend is unable to read with great certainty of the addon produced values. There are many factors such as unstable frame rate.
• The code where used the following construct for detecting damageDone, damageTaken, deadGuid values by

globalCounter % COMBAT_LOG_ITERATION_FRAME_CHANGE_RATE == 0 
or
globalCounter - lastDied > COMBAT_LOG_ITERATION_FRAME_CHANGE_RATE

• The given code were not respected the COMBAT_LOG_ITERATION_FRAME_CHANGE_RATE duration and sometimes ended up showing the cell for 0 or 1 tick time which made the backend impossible to read the values.
• its important to mention that, globalTick can overflow the 24bit resolution so have to account for negative subtraction. Based on the in-game FPS. With 60fps it can occurs about every 48-72 hours(if i did the math correctly)

The new code:

• Adds more complexity, but it adds more reliability as well.
