Source/Installation of `vlcore` library in `m3-spatial/lmm/seem/extract.py`

[Unukalhai727]

Hi,

I was looking through the code in m3-spatial/lmm/seem/extract.py and noticed that the vlcore library was used in the script.

Could you please clarify where this vlcore library comes from? I cannot find it on PyPI or common Python package repositories. Is it a custom internal library, a submodule, or perhaps available from a specific source or repository that needs to be installed separately?

It would be very helpful to understand how to set up the environment correctly to run this script.

Thanks!
