Structs should honor rfl::Skip.

[jadamwilson2]

I would like to attach additional fields to a struct that cannot be serialized or written to a database. For example, I have one table with a number of rows with foreign keys to another table. I would like to load one table, store a vector or map of references to the sub entries. An example might look like:

struct Car {
...
};

struct Person {
  std::string name;
  rfl::Skip<std::vector<Cars>> owned_cars;
};

When loading the data, I want to manually populate the owned_cars field, but it should not be serialized.

@jadamwilson2 , I think this makes a lot of sense.
