Fix benchmark data - galactic coordinates mix-up

km3net_testdata/data/astro/antares_coordinate_systems_benchmark.csv

 # benchmark table from http://antares-wiki.in2p3.fr/doku.php?id=benchmarks_astro
 # values were obtained with astro on 2010-07-15, svn revision 5525
+# The gal_lat and gal_lon values for the last 7 entries are mixed up in that table
+# and fixed in this file (2020-10-27 by tgal). The wiki might not be updated yet.
+#
 # units: [deg]
 # theta, phi: track in horiz. UTM
 # zenith, azimuth: Source in horiz. UTM
 # DEC/RA: source in equatorial coos.
 # gal_lon, gal_lat: source in galactic coos.
