update cli

[not-lain]

TLDR; this pr allows the cli command to run anywhere in your machine.

this is an updated version of the cli command it should allow people to run the matanyone2 cli command from anywhere in the machine since checkpoint no longer depends on the local path and instead uses the HF download directory.

I also switched to using the inference to use process_video method.

future users can now from anywhere in their machine run the following commands to setup and run matanyone2

# initialize the directory (only works in dirs with no pyproject file) 
uv init
# install the library (or from not-lain if you want to test before merging) 
uv add matanyone2@git+https://github.com/pq-yang/MatAnyone2.git
# get full info about the parameters
 uv run matanyone2 --help
# run the inference
uv run matanyone2 -i inputs/video/test-sample1 -m inputs/mask/test-sample1.png

Thanks @not-lain for the contributions to improve the CLI usage!

There is a small environment issue affecting hugging_face/app.py that needs to be fixed before merging. Please feel free to take a look 😊
