Add SOLIS LOS photospheric magnetograms as alternative to HMI #14

GONG magnetograms have terrible resolution

We should add SOLIS LOS photospheric magnetograms as an alternative to HMI and GONG. e.g., http://solis.nso.edu/pubkeep/vsm_current_m630l_hr.fits.gz

So the order of display should be:

  1. HMI
  2. SOLIS photospheric
  3. GONG
  4. ... any thing else?

Original comment by Shaun Bloomfield (Bitbucket: s_bloomfield, GitHub: Unknown):

I definitely agree that we should be pulling down the SOLIS photospheric magnetograms as they are much better resolution, but GONG gives better full-day time coverage. So, we need to be careful with the logic applied to selecting which image to display.

From past discussions I recall that one of the goals/remits of SolarMonitor is to show the most up-to-date conditions. On occasion, that will mean that worse resolution data is preferentially displayed. However, I think that we only step down through the instrument priority order if there is no data from the higher priority sources.
