Enhance Exception Handling for I/O Errors

[umegane]

In Limestone, the error handling for I/O errors was insufficient, particularly for public APIs, where it was unclear what exceptions might be thrown, leading to improper exception handling on the caller side.

To address this issue, the following modifications were made:

1. The locations where I/O errors can occur were carefully reviewed, and error handling was improved.
2. Custom exception classes, limestone_exception and its subclass limestone_io_exception, were created to throw appropriate exceptions when I/O errors occur.
3. For public APIs, we clarified in the documentation where limestone_exception might be thrown due to I/O errors. APIs where no exceptions are thrown were marked with the noexcept keyword.
4. Logging was added to ensure that error occurrences are properly recorded.
