Add domain exclusion zones via windIO

[cfrontin]

Adds exclusion zones that mirror boundaries using the windIO setup.

[Copilot]

Pull request overview

This PR adds support for domain exclusion zones in wind farm layouts through the windIO configuration system. The implementation mirrors the existing boundary distance handling and provides a new component for calculating distances between turbines and exclusion zones.

Key Changes:

• New FarmExclusionDistancePolygon OpenMDAO component for computing turbine-to-exclusion-zone distances
• Comprehensive test suite for single and multi-polygon exclusion zones including derivative validation
• Visualization support for rendering exclusion zones in layout plots

Minor comments, not really blocking. I did not math check your tests, but I assume you did.

I would prefer to see this test use a case closer to the expected use case. In this test, all turbines are inside the exclusion zone. Could you make the exclusion zone smaller, with maybe just one turbine inside and at least one turbine right on the boundary and other turbines outside?

all these tests, not just this one

tests updated in 44c1b37. failing one in a way I can't explain.
