CI tests failing

[bricksdont]

The tests have been failing for some time now,

either because simple-video-utils is not available:

ERROR: Could not find a version that satisfies the requirement simple-video-utils (from pose-format) (from versions: none)
ERROR: No matching distribution found for simple-video-utils

or because of mediapipe missing or the wrong version installed:

ERROR pose_format/utils/generic_test.py::test_detect_format[holistic-holistic] - ImportError: Please install mediapipe with: pip install "mediapipe<0.10.30"

@AmitMY are you planning to publish simple-video-utils for other Python versions as well on Pypi?

and regarding the mediapipe error,

the CI runs pip install .[dev], but the dev target still does not have a pinned version mediapipe:

pose/src/python/pyproject.toml

Line 26 in e535f69

"mediapipe",

re simple-video-utils it is on pypi https://github.com/sign/simple-video-utils - https://pypi.org/project/simple-video-utils/
perhaps it is because the minimum python is 3.10.

so i would need to add a test matrix for 3.8 ... 3.13 for that lib, and make sure it works, then publish it with >=3.8 similar to pose format

as for mediapipe, we can also install mediapipe if the tests require it.

I was still unsure why for the dev install target, mediapipe is not pinned, so I made this a PR: #198
