feat(config-reader): add models-dir and device-mode configurations

Add new configuration options for custom model directories and device modeselection. This allows users to specify the directory where models are stored
and choose between CPU and GPU modes for model inference. The configurations
are read from a JSON file and can be easily extended to support additional
options in the future.

-#### Install Git LFS
-Before you begin, make sure Git Large File Storage (Git LFS) is installed on your system. Install it using the following command:
-
-```bash
-git lfs install
-```
-
-#### Download the Model from Hugging Face
-To download the `PDF-Extract-Kit` model from Hugging Face, use the following command:
-
-```bash
-git lfs clone https://huggingface.co/wanderkid/PDF-Extract-Kit
-```
-
-Ensure that Git LFS is enabled during the clone to properly download all large files.
-
-
-
-Put [model files]() here:
