Closes #2268 - Fixes Sporadic failures of Parquet segarray_write test with gasnet

[Ethan-DeBandi99]

Closes #2268

This PR updates the processing for SegArray reads and writes to prevent memory corruption errors from occurring. From my testing, these were the errors I was seeing. They were different than those reported. Either way these errors needed to be resolved as they occur mainly when a locale only contains empty segments.

• Adds handling for writing to locales with segment values where all segments are empty
• Adds handling for reading from files with only empty segments
• Adds better memory management and cleanup of memory used during processing
• Updates testing file names
• Adds column with strings longer than 1 character for testing

If these updates do not also address the specific reported issue, we will reopen the issue and continue troubleshooting.

All the logic looks good to me! It looks like github is complaining about a merge conflict. Once that gets resolved and the leftover prints get removed, this should be good to go

Looks good
