Add LAI to global data selection

[BSchilperoort]

This PR adds LAI data to the global data selection. LAI comes from the fapar dataset, downloaded using the CDS. (The CDS fapar data has download issues, but this is under investigation by ECMWF).

Currently LAI data for 2014 is on Snellius. (same as ERA5 and ERA5-land).

Tasks:

• [x] data loading routine
• [x] tests, test data
• [x] download script, instructions
• [x] data parse notebook
• [x] files to snellius

Got an unexpected error when running the download_FAPAR_LAI.py script. Any idea about it? It doesn't seem to be an error related to this PR 😿 .

There might be a typo in there, while I trying to make a working script. However, the fapar dataset has issues on the CDS, so you can probably skip that part for now until ECMWF/Vito fixes this.

The downloads are slow and unstable due to the data not being hosted on the ECWMWF's servers, but instead on a Vito server.

When you make a request using the CDS api, the CDS backend downloads the files from the vito server, and once they're downloaded send them to you. However, the connection between the CDS server and the Vito server is not stable and can cause the download to fail or be corrupted.

I have raised this issue on the CDS api github repo, and opened a ticket on the ECMWF website.
