Memory leak caused by EasyOCR

### Bug

Hello. I have been experimenting with Docling for a while and am impressed by its performance. Everything runs well in my local environment. The problem is that when I ran the same codes in a container environment, the CPU memory kept increasing until it went OOM and the container killed itself. I have figured out the problem is a memory leak caused by the `reader.readertxt` function in EasyOCR, and a similar issue https://github.com/JaidedAI/EasyOCR/issues/815 was reported but unsolved under EasyOCR's repo.

### Steps to reproduce

The piece of code I used is
```python
pipeline_options = PdfPipelineOptions()
pipeline_options.do_ocr = True
pipeline_options.do_table_structure = True
pipeline_options.table_structure_options.do_cell_matching = True
pipeline_options.ocr_options = EasyOcrOptions(force_full_page_ocr=True, lang=['es'])
pipeline_options.accelerator_options = AcceleratorOptions(
num_threads=8, device=AcceleratorDevice.CPU
)
doc_converter = DocumentConverter(
format_options={
InputFormat.PDF: PdfFormatOption(pipeline_options=pipeline_options)
}
)
conv_result = doc_converter.convert(input_doc_path)
```
My local environment is MacOS (M3) with 18G RAM. My container environment is Linux with 18G memory limit.
