Remove unused definitions

[SebastianStehle]

For one area of my generated SDK I have created the client code manually. Therefore I remove these operations from the open api document:

var document = await OpenApiDocument.FromUrlAsync("https://localhost:5001/api/swagger/v1/swagger.json");

foreach (var path in document.Paths.Keys.ToList())
{
    if (path.StartsWith("/api/content", StringComparison.OrdinalIgnoreCase))
    {
        document.Paths.Remove(path);
    }
}

is there an easy way not to generate DTOs for unused schemas?
