Create a STAC item for HLS_VI granules

[SwordSaintLancelot]

PR is created to create an STAC item for the HLS_VI granule.

Script description

generate_stac_items.py is the script that generates a STAC item for the HLS_VI granule.
In order to create the item, the script requires the cmr xml file of the HLS_VI granule along with the file name that should contain the STAC item in JSON format. It also requires the DAAC information from where the data is being fetched.

Other arguments and information are provided within the script in the form of function descriptions and arguments.

Please add some unit tests and also expose an entry point for the command line (see https://github.com/NASA-IMPACT/hls-vi/blob/main/setup.py#L15-L20)

@SwordSaintLancelot, you can run linting and test locally by running the following, as mentioned in the README.md:

make test

That should show you the same errors as the CI build, so you can address them locally before pushing your changes.

You must also add missing dependencies to the install_requires list in setup.py. I see that you're missing pystac, geojson, and perhaps others.

@chuckwondo The code has been updated and checked. All the tests are passed. You can review it and let me know if there are any changes needed.

[chuckwondo]

Looks good.

@chuckwondo @SwordSaintLancelot , received href for VI from LP:

I believe the correct URL should look like this for VI: https://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-public/HLSL30_VI.020/ HLS-VI.S30.T47UNU.2024046T042851.v2.0/ HLS-VI.S30.T47UNU.2024046T042851.v2.0_stac.json

I will update this URL in the code and push the changes.
