TypeError in create_grid_input.py: Mismatch in save_pkl_file arguments

# TypeError in create_grid_input.py: Mismatch in save_pkl_file arguments

## Issue Summary
A TypeError is occurring in the `create_grid_input.py` script due to a mismatch between the number of arguments in the `save_pkl_file()` function definition and its usage.

## Detailed Description
When running the `create_grid_input.py` script, the following error is encountered:

```
File "/Users/i_manav.gupta/VGT_V4/VGT/object_detection/create_grid_input.py", line 215, in
save_pkl_file(grid, args.output, f"page_{page}", page, args.model)
TypeError: save_pkl_file() takes from 3 to 4 positional arguments but 5 were given
```

This error indicates that the `save_pkl_file()` function is being called with 5 arguments, but its definition only accepts 3 to 4 arguments.

## Root Cause
The root cause of this issue appears to be a discrepancy between how the `save_pkl_file()` function is defined and how it's being called in the script.

## Impact
This error prevents the script from executing successfully, which likely interrupts the process of creating grid inputs for the object detection module.
