fix: can't read records

[MicBun]

resolves: #144

This pull request introduces a significant update to the task_read_records function in the src/tsn_adapters/blocks/tn_access.py file. The update aims to enhance the function's flexibility and robustness by allowing it to handle both ISO dates and Unix timestamps.

Enhancements to task_read_records function:

• Added support for both ISO dates and Unix timestamps by introducing the is_unix parameter, which determines the date format to be used.
• Updated the function signature to include a retry mechanism with specified retry conditions and delay.
• Included detailed docstrings to improve code documentation and clarity, outlining the function's arguments and return value.
• Implemented conditional logic to handle the conversion and processing of dates based on the is_unix parameter.
