Added more tuple sizes for web::Path for OperationModifier impl

[TobiasDeBruijn]

Hi there,

This PR adds more tuple sizes (8 more), to support more tuple sizes.

Reasoning

Quite simple, I ran into the limit of 5, and expect to be using a bit more soon too :)

Backwards compatibility

This PR does not affect backwards compatibility

Thanks.

Before you merge, something weird is going on. The following signature:

#[api_v2_operation]
pub async fn update(data: web::Data<Arc<AppData>>,
    web::Path((organization_id, location_id, room_id, controller_id, sensor_id, alert_id)): web::Path<(i32, i32, i32, i32, i32, i32)>,
    payload: web::Json<UpdateAlert>,
    session: Session
) -> Result<Empty>

generates the following YAML (Converted by editor.swagger.io from the original JSON):

      parameters:
        - in: path
          name: ''
          required: true
          type: integer
          format: int32
        - in: path
          name: organization_id
          required: true
          type: integer
          format: int32
        - in: path
          name: location_id
          required: true
          type: integer
          format: int32
        - in: path
          name: room_id
          required: true
          type: integer
          format: int32
        - in: path
          name: controller_id
          required: true
          type: integer
          format: int32
        - in: path
          name: sensor_id
          required: true
          type: integer
          format: int32

What happened to 'alert_id` here (and why?), and why is the first param empty?

Edit: Nope nevermind. That is my own stupidity. The path in the route() call elsewhere did not include the alert_id parameter. Good to merge then.
