[FEAT] Create API call that returns max level of operatives involved

Is your feature request related to a problem? Please describe.
This feature is the result of trying to create rapid answers to important questions.
How many aerial means were used in January 2020? And in 2019?

Describe the solution you'd like
An API call that returns, for the time interval and optional location filters (district,county, parish), the maximum value of man, vehicules, and aerial means involved

Hi @JorgeMiguelGomes

Just a question, when you say the maximum value by type is relative to a specific incident or it's only relative to date?
For instance we have the following 3 incidents for day X on County Y and i will consider only the overall stats without getting the Incident that have the highest usage of means:

Incident	Man	Veh	Aerial
Incident A	50	10	2
Incident B	60	14	5
Incident C	35	7	12

And the endpoint needs to return a reply like:

{
    man: 60
    veh: 14
    aerial: 12
}

Hi @rubemlrm, thank you for your interest in contributing to this issue.
The idea here is to get the maximum number of means involved, at any given time.

When a fire starts the means will grow, reach its peak, and then will become smaller.
What is needed is to find that peak - for each type of means - and return that.

So let's say that during the month of August the max value of aerial means was 14. The API should return that value, along with the fire information, including the hour when that happened.
