Fix 3DE vec3d division issues for Copy/Export Tracks tool.

The original traceback reported was:

Traceback (most recent call last):
 File "<string>", line 1071, in <module>
 File "<string>", line 164, in main
 File "<string>", line 594, in generate
 File "<string>", line 1066, in _generate_v4
 File "<string>", line 897, in _generate_v2_v3_and_v4
 File "<string>", line 398, in _remove_rs_from_2d_point
 File "<string>", line 290, in _apply_rs_correction
TypeError: unsupported operand type(s) for /: 'vec3d' and 'float'

When using the "copy_track_mmsolver.py" (v1.9) tool in 3DE R6 on
Windows.

The fix is two fold;
1) do not perform maths on integer numbers when floats are expected.
2) Fall back to float-float division per-component in a vec3d to avoid
the use of 3DE's vec3d operator overloading - in case this happens again
the future.
