--watch flag doesn't work

[Kazz3r24]

When attempting to use the --watch feature on a directory, it processes all files in the directory as intended but doesn't wait for new files to appear in the directory to continue processing. It's as if the --watch flag is being ignored or was removed from the script?

The syntax used in this case was:
h265ize -d h265 -v -m medium -q 24 --normalize-level 0 --debug --10bit --watch

This is how the use of the flag is indicated in the readme.
