Adding simple H5 scoring example

[NickGeneva]

Earth-2 MIP Pull Request

Description

Adding a Jupytext Notebook for showing how to use the H5 datasource for scoring a model over a year's worth of data. Its still a pretty lightweight demo, but at least gets the process across. Can easily be expanded to comparing the accuracy of multiple models.

Makes some assumptions about the data, but at least provides some information. Eventually to integrate into the docs build. that will be a process of its own.

Closes: https://github.com/NVIDIA/earth2mip/issues/98
