Enable reproduction of climatologies before 2022-01-10 with 0080v2 data

[mfisher87]

We're currently using NSIDC-0001&0007 for data before 2022-01-10, but we should be able to use one dataset for the entire time period.

From Mike in #30

the code to generate all those .bin files from nsidc-0001 & -0007, I think, has been lost, and thus hurts the reproducibility of this science. :yikes: It's another issue, perhaps, worth it to reproduce that old code (it'd have to be based upon the v2 data now) to ensure that the old climatologies really are being reproduced completely in v2.
