[nbhatt] Fix JSON parsing to handle multi-line AddFile objects in delta-sharing response

[nbhatt-atlassian]

This issue was found when one of our customers couldn't do a simple

import delta_sharing

share_file_path = "<share_path>"
table_url = f"{share_file_path}#<table>"

# Attempt to load the table into a pandas DataFrame
df = delta_sharing.load_as_pandas(table_url)

The delta-sharing library is encountering JSONDecodeError exceptions when attempting to parse JSON data from a server response. The issue arises because the client code assumes that each line in the response corresponds to a complete JSON object. However, the JSON data contains embedded newline characters within string values, causing JSON objects to be split across multiple lines. As a result, parsing each line individually fails, leading to JSONDecodeError exceptions.

I wasn't able to figure out how to run Integration Tests locally but if someone could point me in the right direction here so I can write tests for this - please let me know :)
