[Feature] Create a convention interface for NaturalId (INaturalIdConvention)

Hi,

I'm looking for an interface like INaturalIdConvention, so I can apply the same casing style to the names of the columns that make up the natural id of my table.

NaturalId().Property(t => t.SomeProperty, /* Make column name snake case */); // <-- I want to move these to a convention.

Is there some way to do it using conventions? Or just manually for each natural id map?

I've fixed a bug where conventions were not applied to members of <natural-id>. It should be available on NuGet shortly.
