Update jplhorizons columns

[mkelley]

JPL Horizons has had a few additions to their columns. Update astroquery to match. Based on the Horizons documentation, the new quantities are:

       44. Apparent target-centered longitude of Sun (L_s)
     * 45. Inertial frame apparent RA & DEC
       46.   Rates: Inertial RA & DEC
     * 47. Sky motion: angular rate & angles
       48. Lunar sky brightness & target visual SNR

Also add units to hour_angle, solartime, and siderealtime. (bugfix)

Thanks @mkelley!

Not sure what went wrong here that bloated up the diff this badly. Could you maybe rebase and remove that second to last commit that only added noise by reformatting, but haven't really fixed the whitespace issue?

[mkelley]

Shucks, I had worked so hard to keep black from reformatting the file... but missed it one time.

All looks good! Thanks @mkelley!
