cmd: add ejson2csv

ejson2csv processes JSON output into CSV, by default filtering for
diagnostics with messages.

The CSV produced has these 5 columns, which are sometimes empty when
they don't apply (e.g., errors have no position, other is just module
path and its index):
       ModulePath mpIndex Message/error meIndex Position

for example (line wrapped, comma separated):

storj.io/uplink,20372,
"conversion between structs from two different packages from different
modules storj.io/uplink and storj.io/common, from
storj.io/uplink.SharePrefix to storj.io/common/grant.SharePrefix",0,
