Add Cryosat-2 (CryoTEMPO-EOLIS) Swath Thematic Point Product

[weiji14]

Just found out about the “CryoTEMPO-EOLIS: Elevation Over Land Ice from Swath” project, Looks like a more accessible way of getting Cryosat-2 radar altimetry data, though it's still pretty limited for the Antarctic (currently 2020 May only).

Specifically, the Swath Thematic Point Product (EOLIS POINTS) appears to be a promising dataset that should nicely compliment the ICESat-2 point cloud processing in this repo. Should look into it in the long-term (read: early 2021 after my PhD).
