[NSFS] Fix list objects ordering to follow AWS S3

[tangledbytes]

Explain the changes

This PR replaces the pre-existing sorting functions in listObjects (NSFS) with a new one which tries to treat strings as UTF8 encoded Uint8Arrays. This helps with sorting the array of strings in a similar fashion as AWS S3 does.
