This implements an option to use linear interpolation to find the liquid isotherm (TL) before extraction the melt pool geometry. This provides a smoother response that is less sensitive to mesh geometry and provides a smoother convergence when refining the mesh.

This is implemented as an additional feature to MP_Stats (though largely uses the same logic under the hood, with only a couple logic branches), because I've noted this slows down the solution significantly (up to 4x!) and the increased resolution of melt pool geometry may not always be necessary.

- For small cases this did not noticably change solution time
- For a larger case, this changed time from 60 s to 232 s. Not great, so will try to fix that.

- Only marginally faster (~3-5%) but makes sense to be consistent between the codes
