rDDATASET3df08fd71759: Add support for limited row numbers in ORC files

Summary

Make it possible to specify a maximum number of rows a table can store
in a single ORC file. The limit can only be set on main tables for now
(i.e. cannot be specified for tables like revision_history or
directory_entry).

This can be set by configuration only (no extra cli options).

Depends on D7389.

swh/dataset/exporters/orc.py
159–163	Actually I don't think this is a big deal here. If we want to fail, it should be a check done before starting to export anything.

check for max_rows validity at ORCExporter class instanciation + copyrights
