Issue with boolean custom types in generated ffjson file

[acabarbaye]

As per my API definition, I have defined some custom types which actually are booleans:
e.g.

type EmbedParam bool

in the generated code, I get

	var tval bool

	if bytes.Compare([]byte{'t', 'r', 'u', 'e'}, tmpb) == 0 {

		tval = true

	} else if bytes.Compare([]byte{'f', 'a', 'l', 's', 'e'}, tmpb) == 0 {

		tval = false

	} else {
		err = errors.New("unexpected bytes for true/false value")
		return fs.WrapErr(err)
	}

	j.Embed = &tval

tval is defined as a bool instead of EmbedParam like Embed, meaning I get the following compilation error:

.\****_ffjson.go:***:12: cannot use &tval (type *bool) as type *EmbedParam in assignment

Could the local variable be defined using the custom type i.e. var tval EmbedParam?
