Celestrak rework

[jmurphy6895]

• Grab F10.7 Flux, Ap and Kp indices, derived metrics and some solar indices from Celestrak SW instead of Fluxtable and Kp_ap_Ap_SN_F107_since_1932.
• Added kwargs flag to urls() to give option to pull last 5 years of data or the entire history since 1957 from Celestrak
• Also shifted F10.7 flux 8 hours since the metric is measured at 20:00
• Fixed Test in JB2008 Indices that was failing

Hi @jmurphy6895 !

This PR is awesome! Thank you very much. I just have some comments related to code styling that I can change myself :)

I will merge as soon as the tests pass.

By the way, I am testing the code here, the file SW-All.csv has just 2.6 MiB. Should we really add that keyword all_history just for the Celestrak file? Wouldn't be better to keep the API simple and just download everything? What do you think?

Awesome! Thanks @jmurphy6895 ! Let's see if tests pass. I have no further comment.

Done! Thanks!
