Need cleaned gst and AST output files for the metal_small example

[karllark]

With the change to having the cleaning of the photometry and AST results file happening outside of the BEAST, updated metal_small observation and AST output star files needed.

Is there code for doing this cleaning in the BEAST tools directory?

Also would be good to have the 500 stars used for the metal_small example be sorted by brightness in an optical band to provide a straightforward way to cycle through fits for different brightness stars. If the 500 stars spanned the range of brightness in the example metal field, this would be great.
