Exclude from serialize process the ignore fields

[glucaci]

If we haven an object with ignored field e.g.:

expected.MatchSnapshot(options => options.IgnoreField("Content"));

the field "Content" should not be serialized because may have a type which is not serializable.

any movement on this?

My proposal is to create a new match option called .ExcludeField("Content"), which removes the specified field(s) from the snapshot. The IgnoreField is really only to ignore the field, but not change the snapshot output.
