Graph ionosphere numeric data

Use a URL similar to this to pull data into python:

https://lgdc.uml.edu/common/DIDBGetValues?ursiCode=PA836&charName=MUFD,hmF2,hmF1&DMUF=3000&fromDate=2023%2F03%2F10+14%3A00%3A00&toDate=2023%2F03%2F10+15%3A50%3A00

Get back a report like the following to be parsed and used:

QSL cards using USPS postcards

Create a template file to make this simple. Document how to print on both sides.
The USPS post cards can be found at
https://store.usps.com/store/product/cards-envelopes/mallard-double-reply-stamped-card-S_250704

The initial template is in the repository
