[Question] How do I handle the following fields in the golang code？

I would like to generate the following file.

```
locals {
region_vars = read_terragrunt_config(find_in_parent_folders("region.hcl"))
region = local.region_vars.locals.region

project = "abc-dev"
account_number = "443813933915"
services = [
"apiserver",
]
additional_statements = [
{
"Sid" : "",
"Effect" : "Allow",
"Action" : [
"secretsmanager:GetSecretValue",
"kms:Decrypt"
],
"Resource" : [
"arn:aws:secretsmanager:${local.region}:${local.account_number}:secret:*",
"arn:aws:kms:${local.region}:${local.account_number}:key/*"
]
}
]
}
```

But in my golang code, I can define a structure as following
```
type ProjectHcl struct {
Locals Locals `hcl:"locals,block"`
}

type Locals struct {
Project string `hcl:"project"`
AccountNumber string `hcl:"account_number"`
Services []string `hcl:"services"`
}
```

How can I deal with other fields `region_vars`, `region`, `additional_statements`?

Start with the ProjectHcl and Locals declarations shown in the issue, then read the HCL decoding documentation for handling the additional fields in the example. Confirm the documented approach against the example configuration and explain how region_vars, region, and additional_statements should be represented.
