Update sumologic.yml 
The commit from vihreb on October 6, 2020 (51df5ad876) removed some items from the allowed fields list for the sumologic backend (51df5ad876/tools/sigma/backends/sumologic.py (L161)) with the expectation that they are included in the sumologic config, however the default sumologic config does not reflect that change. This breaks the parsing of maps from rules. For example, when trying to run sigmac on a rule with multiple EventID values, the result is an error that states "argument of type 'int' is not iterable."

I suspect that this change in the behavior of the backend was made to accommodate for new sumologic-cse config which may not need the additional allowed fields that the regular sumologic config does. As such, I think it would probably make the most sense to re-add these fields to the sumologic config file rather than directly back into the backend for sumologic.

Note: In the config, I did not include those fields that are presently hard coded in the allowed field list in the sumologic backend (e.g. _sourceCategory and _view were removed). I also removed "sourcename" since from what I can tell, the syntax that vihreb added to the sumologic backend "_sourceName" is actually correct.

1e5ee5823c Fix for indentation issue 
Wrong indentation of line 182 meant that even where config options
were given, the default per backend was being used, rendering
custom config useless.

Brad Kish
8b3b312c4e Proposed fix for https://github.com/Neo23x0/sigma/issues/889 
This change removes dns events from the network connection category. The
one change is that sysmon_regsvr32_network_activity.yml needs to test
the network connection category separately from the DNS event id.

203aa192c7 Fix multiple references to default field mapping in same rule 
If there is a default mapping specified for a fieldmapping and that field is
referenced multiple times in the rule, the default mapping will be "pop"ped
and return the unmapped key on subsequent uses.

Don't pop the value. Just return the first entry.
