Question - Write Remain

I'm trying to dynamically create some HCL files from golang.

I'm trying to write the following objects

```
type Modules struct {
Modules []*Module `hcl:"module,block"`
}

type Module struct {
Name string `hcl:"name,label"`
Source string `hcl:"source"`
Options interface{} `hcl:",remain"`
}
```

Using the follow, I'm not able to generate the remaining attributes
```
func Encode(val interface{}) []byte {
f := hclwrite.NewEmptyFile()
gohcl.EncodeIntoBody(val, f.Body())
return f.Bytes()
}
```
##Output
```

module "bar" {
source = "./bar"
}

```

##Expected
```

module "bar" {
source = "./bar"

foo = "bar"
bar = ["foo", "bar"]
}

```

Start with the hclwrite.NewEmptyFile and gohcl.EncodeIntoBody calls shown in the issue, then reproduce the provided Modules and Module values. Trace how the `hcl:",remain"` field is handled during encoding. Done means the generated module block includes the remaining foo and bar attributes shown in the expected output.
