[FEATURE] Damage dealt in fight

[Bouillot-Rngk]

Is your feature request related to a problem? Please describe.
Feature is just not there and could be a nice improvement

Describe the solution you'd like
An asset similar to the "gold diff from start" feature but with damage dealt on last fight could improve the "in game analysis" for casters. It's a complex feature, the main problem being "When does a fight start ?", and "Does the memory cache reading give access to this information ?"

Describe alternatives you've considered
To answer the question of "When does a fight start" i have two main ideas :

• Manual button on app that allows script to start counting damage from one point of time (or retaining the total damage dealt info from this point), second activation (or an other button) will show the damage graph
• Automatic scripts that start counting damage from one point of time when a threshold is activated for two or three champs, and a button that can show the damage graph

Would defently be a very nice addition.
Memory reading is outside of my knowledge, so @floh22 would have to get the reading for Damage Dealt inside of the game
