Bug in optimize_submap

[lemonci]

The submap optimizations are

MAGiC-SLAM/src/entities/mapper.py

Line 114 in 4ac5aa9

for iteration in range(iterations):

prune_points is supposed to be called at half of all the iterations or the end:

https://github.com/VladimirYugay/MAGiC-SLAM/blob/4ac5aa92ab70139546b42927b62e4f2fd6940222/src/entities/mapper.py#L138C1-L138C80

However, the maximum of iteration will be iterations - 1, instead of iterations.

@VladimirYugay Vova I think you should update the code, it is an easy fix.
