List a project's time series (rain gauges, hydrographs, tides) — never their rows.

Each series: id, name (a rainfall polygon binds to its gauge by this exact name), series_type, units, timezone, row_count, first_timestamp and last_timestamp. The data rows themselves are dropped (a project's list is megabytes); fetch one series with the REST API (GET /projects//time-series//) if you need its values.
