Add user input tolerance and extrapolation warning to MorphSqueeze

[Luiskitsu]

Currently, test MorphSqueeze uses fixed tolerances when validating interpolated and extrapolated results, which can be too strict or too loose for real data.
Proposed changes:
Add tolerance user input parameter.
After computing y_morph_out, compare the extrapolated segments to the target using the user’s tolerances and emit a warning if any point exceeds those thresholds.
