Currently, the code looks at the enumerate index `i` to see if a fast5 file was found in the given directory. However, if a directory does not have any files in it, then the enumeration loop won't get started and the `i` variable will actually be unbound, so the code as written would raise an `UnboundLocalError`. If there is a single fast5 file in the directory, then `i` will be valid, but it will be `==0`. I've updated the logic to use a simple flag to indicate when we have actually inserted a fast5 file into the Queue during this loop.

If there is a single fast5 file in the directory, theniwill be valid, but it will be==0, causing the current code to error saying that no fast5 files were found.I've updated the logic to use a simple flag to indicate when we have actually inserted a fast5 file into the Queue during this loop.
