Mozjpeg not found crash

I get the following error on any run of the program: ``` > picopt --help Traceback (most recent call last): File "/home/calum/.local/bin/picopt", line 5, in <module> from picopt.cli import main File "/home/calum/.local/pipx/venvs/picopt/lib/python3.11/site-packages/picopt/cli.py", line 10, in <module> from picopt import PROGRAM_NAME, walk File "/home/calum/.local/pipx/venvs/picopt/lib/python3.11/site-packages/picopt/walk.py", line 16, in <module> from picopt.config import TIMESTAMPS_CONFIG_KEYS File "/home/calum/.local/pipx/venvs/picopt/lib/python3.11/site-packages/picopt/config.py", line 37, in <module> from picopt.handlers.jpeg import Jpeg File "/home/calum/.local/pipx/venvs/picopt/lib/python3.11/site-packages/picopt/handlers/jpeg.py", line 12, in <module> class Jpeg(ImageHandler): File "/home/calum/.local/pipx/venvs/picopt/lib/python3.11/site-packages/picopt/handlers/jpeg.py", line 22, in Jpeg PROGRAMS["mozjpeg"], ~~~~~~~~^^^^^^^^^^^ KeyError: 'mozjpeg' ``` I'm running on a Debian Stable system, without mozjpeg installed. I instaled picopt with "pipx install pipopt" about 5 minutes ago. I think there's some issue in the support for running without mozjpeg.
