Allow batching of items when sent to LLM

[makrianast]

Description

The convert_texts_to_vector() function has been updated to support batching. The batch_size parameter, set to 50 by default, determines the number of items per batch. An additional parameter, max_batches, controls the maximum number of allowed batches, with a default value of 2000. When batch_size is set to 0, batching is disabled.

This modification ensures better handling of large datasets, optimizing the function for scalability and efficiency.

Fixes # 56

Type of change

• New feature (non-breaking change which adds functionality)

Testing

A unit test, test_batch(), has been added to validate the batching functionality. It:

• Sends 10 items to convert_texts_to_vector().
• Sets batch_size to 5.
• Verifies that the items are divided into 2 batches of 5 each.

Test Configuration

• Library version:
• OS: Windows11
• Toolchain: 3.10.0
