Fails to decode struct if field is missing

[fogfish]

The library fails to decode a struct if field is missing.

E.g. I do have a struct

type TokenExchange struct {
  Type string `form:"grant_type"`
  Code string `form:"code"`
}

The input string to parse

grant_type=authorization_code&code=xxx&client_id=xxx

The library fails to decode string with an error

client_id doesn't exist in main.TokenExchange

I would expect that library skips client_id.

If you can set ignoreUnknownKeys to true and you won't have this problem anymore.
