Handle "target-is-shorter-then-pinned" case

When the target pinning curve (by default, the dispersion major) is
shorter then the pinned curve, we need to make sure we find still find
the x-intersect for computing returns scalars! Use `Viz.i_from_t()` to
accomplish this as well and, augment that method with a `return_y: bool`
to allow the caller to also retrieve the equivalent y-value at the
requested input time `t: float` for convenience.

Also tweak a few more internals around the 'loglin_ref_to_curve'
method:
- only solve / adjust for the above case when the major's xref is
  detected as being "earlier" in time the current minor's.
- pop the major viz entry from the overlay table ahead of time to avoid
  a needless iteration and simplify the transform calc phase loop to
  avoid handling that needless cycle B)
- add much better "organized" debug printing with more clear headers
  around which "phase"/loop the message pertains and well as more
  explicit details in terms of x and y-range values on each cycle of
  each loop.
