Switch all of the aspherical booleans to the geometry string comparisons about lentil

[zpelgrims]

Removed lens.anamorphic, lens.cylinder_axis_y

Still need to remove lens.aspherical. Need to investigate into the "k" parameter (0 or 1). Why would you ever evaluate an aspherical function, yet pass 0 as the aspherical element? Seems strange

Use an aspherical test file so I can validate that I don't break anything
