3DE Tools - Import Tracks - Allow Users to Choose To Use "3D Bundle Positions"

[david-cattermole]

Problem

When importing 2D Tracks into 3DEqualizer with the "Import Tracks (MM Solver)" tool, the 2D Tracks imported are always set to "Exactly Surveyed" (if a file with such data exists).

Users would like to have the choice to turn this on or off - with it being off by default.

Steps to Reproduce

1. Open 3DEqualizer.
2. Go to "3DE4 > File > Import > Import Tracks (MM Solver)".
3. Choose a file path.
4. Users should now be able to choose on/off if the 3D Bundle Positions are loaded into 3DE or not (like the Maya Load Markers UI allows).
5. Press Ok button.
