Add Lake Ice Regime Data Layer to PDG

[kaylahardie]

This request is about Melanie Engram's (University of Alaska Fairbanks) lake ice regimes dataset.

We heard about this dataset at the big data creation workshop during the google fellows + pdg members meet up in fairbanks in May 2024 (see raw notes here and summary notes here)

The impact of this dataset: helps determine if lakes freeze to the bottom or not - this impacts permafrost, communities, lake ecology

Technical notes about the dataset creation:

• uses sar data
• currently generated using matlab script and python, the scripts need to be updated (old dependencies in matlab code)
• dataset creation doesn't use ml - uses thresholding
• dataset has been created for small regions (ex. Barrow peninsula, fish creek area), hasn't been run on a large scale before. It has only been run on a single computer
• ideally you create this dataset every year

Given these technical details, in order to add a yearly dataset for lake ice regimes: we'd have to rewrite the matlab script to be in python and experiment how we could scale it to larger regions (including validating that the results make sense from a scientific perspective for larger regions).

fyi @lmarini @tcnichol since there would need to be work in rewriting the data pipeline and scaling it. This dataset is lower priority though
