CNX-9753: Add assembly and subassembly objects to Corridors

[clairekuang]

Description & motivation

This pr adds quite a few new civil classes and restructures how corridors are sent from Civil3D:

• CivilBaseline
• CivilBaselineRegion
• CivilAppliedAssembly
• CivilAppliedSubassembly
• CivilCalculatedShape
• CivilCalculatedLink
• CivilCalculatedPoint
• ICivilCalculatedObject interface

Closes #3265

Changes:

• Objects
• Civil converter

Screenshots:

@JR-Morgan could you review the abstract Baseline class?

[oguzhankoral]

LGTM! Seems like we combined alignments and profiles under baselines for corridor which is niiiice.

There are a couple more properties of the objects that we could do with adding.
If you could squeeze this in before the next connector update, that would be much appreciated :-)

[jhdempsey86]

Get another property from the subassembly
string SubassemblyMacroOrClassName = subassembly.GeometryGenerator.MacroOrClassName

This one let's save for another issue to add subassembly objects, as this property should be on a new Subassembly class instead of the AppliedSubassembly class

[jhdempsey86]

Add in following property, and add a new parameter into the constructor to set it
public string SubassemblyMacroOrClassName { get; set; }

[jhdempsey86]

Add property to store the station of this AppliedAssembly and include in the constructor so the value can be set
public double station { get; set; }

[jhdempsey86]

If possible, it would be helpful within the AppliedAssembly object to have the station at which it is applied.
The Civil API doesnt give you this directly, but if you use a for loop to loop through the SortedStations, you can get the station for each AppliedAssembly, You then just need to pass that in when creating the Speckle AppliedAssembly

for (int i = 0; i < sortedStations.Length; i++)
{
    var station = sortedStations[i];

    var appliedAssembly= region.AppliedAssemblies[i];

   CivilAppliedAssembly speckleAssembly = AppliedAssemblyToSpeckle(appliedAssembly, station);

   speckleAppliedAssemblies.Add(speckleAssembly);
}

[clairekuang]

I'll add the station property dynamically, since it's not accessible on the appliedAssembly

[jhdempsey86]

Add in a station parameter
private CivilAppliedAssembly AppliedAssemblyToSpeckle(AppliedAssembly appliedAssembly, double station)

[jhdempsey86]

Pass the station into the function that creates the SPeckle AppliedAssembly:
CivilAppliedAssembly speckleAppliedAssembly = new(speckleSubassemblies, appliedAssembly.AdjustedElevation, ModelUnits, double station);
