[Feature]: Implement FeatureExtensions #131

Prerequisites

• I have written a descriptive issue title
• I have verified that I am running the latest version of the SysML2.NET
• I have searched open and closed issues to ensure it has not already been reported

Description

The FeatureExtensions class in SysML2.NET/Extend/FeatureExtensions.cs contains 16 extension method(s) that compute derived properties for the IFeature interface. These methods currently throw NotSupportedException and need to be implemented.
