Spatial_Engine - Handle nulls

[FraserGreenroyd]

Note, where the method begins with BH.oM - this means it is a Create method.

The following methods need appropriate null handling of their inputs. You can use @BHoMBot check null-handling on a draft PR to check progress if needed - you're ultimately looking for a reduction in errors from the master/main branch. I can run more localised tests to confirm against if needed to confirm specific methods.
