+Get channel information for a given period, combining all runs in that period.

+this channel info takes all runs in this period and creates a combined channelinfo
+for :usability, :is_blinded, :psd_usability, :low_aoe_status, :high_aoe_status, :lq_status, :ann_status, :coax_rt_status only the 'best' value is taken, i.e. the one with the highest priority in the hierarchy
+all the other column entries should remain the same over different runs
+
+all kwargs and filterby can be used as in the usual channelinfo
+
+make sure to include "Tables" by "using Tables" before using this function
