Add MODIS LAI driver & use in experiments

[Espeer5]

Purpose

This PR adds driver utilities to run simulations using MODIS LAI from 2008 as opposed to era5 LAI. Corresponding PR adding MODIS LAI data to ClimaArtifacts is here.

To-do

• Verify MODIS LAI works correctly where used in snowy land benchmark
• Clarify which experiments/benchmarks should use MODIS LAI by default

Content

• MODIS LAI artifact added to Artifacts.toml
• Utility to get the MODIS LAI artifact path added to src/Artifacts.jl
• Utility to construct the LAI function from MODIS LAI data added to drivers.jl

---

• I have read and checked the items on the review checklist.

A note - we dont run the benchmarks by default (or the long runs). You need to add the label to the PR, and then make a push to the branch to trigger them. it's a little annoying but better than running them every time

I'm really not sure what's happening with the buildkite here - no changes to the manifest or anything so I don't know why there are so many failures in the packages/includes/imports?

I had trouble today too, and cleared the depot. I tried rebuilding here - let's see if it runs now

Thank you, this worked!

I believe that incorporating the MODIS LAI seems to have worked correctly - there are certainly differences in the two input datasets though. From our global run plots, here is the LAI from MODIS:

Vs from ERA5:

It's just generally lower than ERA5, with the difference being quite extreme across the northern hemisphere.
