Title: detect .tsv file extension

Per #217, the CLI checks to see if a data file with a `.tsv` file extension is being imported. If so, sets `opts` as appropriate (`opts.csv = true` and `opts.separator = `).

An `importTSV` test was added to `test/tests/cli.js`, modeled on the existing `importCSV` test.
