+Emulate types for `JSON.parse(JSON.stringify(x))` in `SerializeFrom`
+
+Notably, type fields that are only assignable to `undefined` after serialization are now omitted since
+`JSON.stringify |> JSON.parse` will omit them. See test cases for examples.
+
+Also fixes type errors when upgrading to v2 from 1.19
