fix(magic-pdf): add default values and improve warning logs for config optionsEnsure that 'temp-output-dir', 'models-dir', and 'device-mode' have sensible default
values in case they are not specified in the config file.

Improve the model loading mechanism in magic_pdf by implementing a Singleton
pattern to reduce redundant model instantiation. Additionally, enhance the
command-line interface to support input from list files, allowing batch
processing of multiple PDF documents.

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.

Introduce a new feature that allows users to choose between a "lite" and a "full"
model mode for PDF document analysis. The "lite" mode uses a faster, less
accurate model, while the "full" mode employs a higher-precision model at the
cost of speed. This selection can be made through the CLI or API, providing
flexibility for different use cases.

update:Add md make mode config in do_parse.You can control whether the produced md is for NLP or MM by changing the value of f_make_md_mode

fix: The presence of ".pdf" multiple times in the pdf_path results in model_path not matching the expected.
