Fixes ALS017 (IVS-282) (#328)
Browse files Browse the repository at this point in the history 
* fixes continuity calculations for segments on vertical and cant alignment representations

The length of each segment corresponds to the total length along the parent curve.
However, for continuity calculations, we need to provide the total length along the *base* curve.

(IVS-282)

* bump ifcos version; correct the data in unit test file

* use correct values for calculating end gradient

(IVS-282)

* refactor geometry calculations and update IFC test files.

Updated to current geometry evaluation methods for alignment segments.
Adjusted IFC test files to reflect corrections to direction vectors and parabolic segment lengths.
 Updated CI pipeline to use the latest IfcOpenShell build.
