Subject: [PATCH] rhbz#1980800 allow --convert-to csv to write each sheet to a
 separate file

Related: tdf#135762 except only currently implemented for command line use

sample usage:
soffice --convert-to csv:"Text - txt - csv (StarCalc)":44,34,UTF8,1,,0,false,true,false,false,false,-1 sample.ods
where the new (11th!) final token ("-1") enables writing each sheet to a
new file based on the suggested target name so output in this example
is files sample-Sheet1.csv and sample-Sheet2.csv

Only -1 for 'all sheets' vs 0 for existing 'current sheet only' (which
is always sheet 0 from the command line) are currently options but the
token could be expanded in the future to select specific sheets to
export.

Related: tdf#135762 Allow --convert-to csv to specify 1-based sheet number

Same multifile mechanism as for -1 all sheets is used, so

soffice --convert-to csv:"Text - txt - csv (StarCalc)":44,34,UTF8,1,,0,false,true,false,false,false,2 sample.ods

writes a file sample-Sheet2.csv
