Refresh F10.7 and ap data handling with partial data support and automatic updates

Closes #69

[mananapr]

Hi @greglucas, I've pushed another commit based on your suggestions.

• I have removed the partial download functionality because like you said, it is a lot of headache
• I am getting the last observation date from the warnings data like you mentioned.
• I am still keeping the check on file update date to prevent pymsis from re-downloading the SW file each time the program runs in case the end date is not present in the csv file

Let me know what you think.

@mananapr I pushed a commit up to your branch to try and fix up some of the failing tests. Unfortunately, it was more involved than I hoped, so there is a bit more work there than anticipated. It also apparently didn't fix the issue :-/ But it does work locally for me. Feel free to drop that commit if you don't like it and continue on in a different way to try and get the tests to pass too.

Ah, I totally missed that. Will look into the changes, thanks!
