Missing cwlformat requirement

[auberginekenobi]

I think requirements.txt should include a cwlformat dependency? Easily fixable if you used pip to install sbpack but breaks the recommended pipx install since it's installed by default into an isolated environment.

REPRO:

Expected behavior:

> pipx install sbpack
> sbpull
usage: sbpull [-h] [--unpack] profile appid outname
sbpull: error: the following arguments are required: profile, appid, outname

Actual behavior:

> pipx install sbpack
> sbpull
Traceback (most recent call last):
  File "/Users/ochapman/.local/bin/sbpull", line 5, in <module>
    from sbpack.unpack import main
  File "/Users/ochapman/.local/pipx/venvs/sbpack/lib/python3.13/site-packages/sbpack/unpack.py", line 14, in <module>
    from cwlformat.formatter import stringify_dict
ModuleNotFoundError: No module named 'cwlformat'

Workaround:

> pip install sbpack cwlformat cwltool
> sbpull
usage: sbpull [-h] [--unpack] profile appid outname
sbpull: error: the following arguments are required: profile, appid, outname
