main has several iotools changes that would be very nice to have in the tutorial that @AdamRJensen is giving at PVSC this Sunday. I'll plan to merge this PR and make the release tomorrow if there are no objections :)

LGTM!

Thanks @kandersolar. As a housekeeping matter, I recommend we consolidate the 0.12.1 milestone into the 0.13.0 milestone.

For sure, I just ran out of time today.
