Is your feature request related to a problem?

Currently exsanguinate requires manual input of stack count, which

A. Is limited to integers
B. Requires manual recalculation of the amount of stacks by the user every time the application rate or duration changes.

Describe the solution you'd like

Automatic calculation of the running average of the stacks (multiplying application rate by duration, capped at the max amount of stacks), with an override in the config.

Describe alternatives you've considered

No response

Additional context

The calculation could also be used for other non-refreshing stacking DoTs with a max (e.g. Emberwake ignites and Crimson Dance bleeds), and even for non-stacking DoTs with cast rate lower than the duration

El issue no nombra archivos, pruebas ni puntos de entrada. Empieza localizando el cálculo de stack-count de Exsanguinate y su entrada de configuración; después, inspecciona cómo se representan otros efectos de daño en el tiempo acumulables. Se considera terminado cuando el promedio acumulado se calcula con un límite de stacks máximos y puede sobrescribirse en la configuración.
