Wrong calculation in weight if more than 2 radars

[BenNgHKO]

A syntax problem was found in these parts of _get_dd_wind_field_scipy() and _get_dd_wind_field_tensorflow().

This line "cur_array = parameters.weights[i, k]", cur_array and parameters.weights[i, k] point to the same memory address.
parameters.weights[i, k] has changed when editing cur_array, that will only consider the last result of the loop.
