calculate the best quiver on a stats session

[remace]

given a list of shots made with arrows used multiple times,

• [x] for each arrow, calculate the barycentre of the impacts
• [x] find the nearest barycentres.
• [x] integrate it in a view so the result can be displayed to the user

[remace]

to find the nearest barycentres, my idea is to, until the quiver has the right amount of arrows, recursively:

• calculate the convex envelope of the remaining barycentres
• removing the point of the envelope that increases the most the area of this envelope.

see: https://github.com/remace/OC-P13_Archery_Buddy/issues/18#issuecomment-1493325487

my previous idea was a bad one:

• minimizing area of convex hull favors far and aligned points rather than nearer one
• better minimize the minimal bounding circle of convex hull

after testing it seems a much better algorithm.
