Alignment api update (#6817)

Browse Source 
* Some basic COGO survey points functions

* Update alignment api

Includes defining alignment segment by segment, automatic geometry definitions, and automatric stationing and referents

* Fixes bonsai import alignment from csv

* Adds DMS angle conversion functions to COGO api

* Updated per @civilx64 review comments

* Fixes problem with segment representations

* Fixes problem with segment transition codes

* Allows for compound vertical and horizontal curves

* Implements callbacks for referent naming

* Renames angle_from_bearing to bearing2dd for consistency with ifcopenshell.util.geolocation.dms2dd. Removes angle_from_dms because it duplicates dms2dd

* Documents register_referent_name_callback

* Fixes all sorts of problems with Cant/SegRefCurve implementation

* refactor referent unit tests to use a fixture for test setup

* lint with black
