Fetches every row matching a sort and filter, beyond the one page the grid
holds — which is how the grid's CSV export covers the whole result set.
Requests are issued one after another, chunkSize rows at a time, and stop
at whichever comes first: the server's lastRow, an empty response (for a
server that reports lastRow: -1), or maxRows. The requests have the same
wire shape as the grid's own paging requests, always ungrouped — so a
grouped grid exports its rows, not its group summaries.
