Compatible with interface{}

[c625473164]

If meet some fields which not supported such as interface{}, Can we just ignore the err.
For example

struct Test{
A  int
B string
C interface{}
}

I only want A, B filed, just give me C with a nil value

I don't think it's will be good.
If you want to ignore the interface, maybe you can add the skip tag.

struct Test{
A  int
B string
C interface{} `faker:"-"`
}

the struct is sometimes generated by thrift or other tools such as protobuf, so it's not so convenient to add tags
