v1.5.0.0

Welcome to IVyTools v1.5 🎉

This is a major update bringing interactive lens correction, smarter search line handling, improved velocity visualization, and friendlier error reporting. Here's the highlights:

Plus: improved orthorectification for portrait/oblique cameras, add/remove GCP rows directly in the table, documentation migrated to MkDocs, and numerous bug fixes for units, uncertainty, and project loading.

Tip: Existing v1.x projects will load normally. Reprocessing is recommended to benefit from the search line clipping and ortho improvements. Older projects using 3D rectification will need to be review, as the new 3D method will be slightly different (XS will move).

Full details in the v1.5.0.0 Release Notes.
