Anchors

[fmormer]

This pull request includes a number of upgrades and new features developed under FAModel_anchors, focused on the anchor module and its integration with the overall FAModel workflow. Key additions include:

• New anchor examples for anchor methods covering all anchor types and soil stored in examples/05_Anchors
• Enhancements to all capacity models and support functions - Improved plotting and soil-handling functions
• New anchor installation models for most anchor concept - ongoing process
• Anchor class modifications - ongoing process
• Alternatives for the getSizeAnchor methods within the Anchor class
• New exception handling load limitation when soil capacity exceeds applied mooring loads
• Extensive refactoring and cleanup across multiple modules

These updates are intended to improve the flexibility and reliability of anchor design workflows. All changes have been tested locally using the available test suite but there might be some incompatibilities under the radar that might raise with users feedback.
