Duplicate responses fail compilation (http4s framework)

Hi,
I'm working on a project with http4s and guardrail. When I generate both server and client code, I end up with duplicate response models in the same package, which of course fails compilation ("GetUserResponse is already defined as class GetUserResponse", "GetUserResponse is already defined as object GetUserResponse").

Here's an example of yaml:

```yaml
openapi: '3.0.2'
info:
title: User example
version: 1.0.0-SNAPSHOT

paths:
/user:
get:
x-scala-package: users
operationId: getUser
responses:
200:
description: 'OK'
content:
application/json:
schema:
$ref: '#/components/schemas/GetUserResponse'

components:
schemas:
GetUserResponse:
type: object
properties:
user:
$ref: '#/components/schemas/User'
User:
type: object
required:
- name
properties:
name:
type: string
```

Here's an excerpt of my `build.sbt`:

```scala
Compile / guardrailTasks := List(
ScalaServer((Compile / resourceDirectory).value / "api.yaml", pkg = "api.routes", framework = "http4s"),
ScalaClient((Compile / resourceDirectory).value / "api.yaml", pkg = "api.routes", framework = "http4s")
)
```

I could define different values of `pkg` for server and client and prevent the compilation error, but this would result in duplicate code being generated for the same API...

Is this a correct and known behavior?
Thank you in advance
