Combination of compact & excludeSummaryFromExport props breaks CSV Export

[Smoothsmith]

If you enable both of these props, then any rows that get compacted are treated as totals and get excluded from the CSV Export.

I can resolve it by making these changes in the library code (Did it directly in my node-modules for the moment):
if(self.compact && numSubDimensions == 1) {
subRow.includeInExport = true;
} //Inside subRows.forEach before the row is pushed.
https://github.com/davidguttman/node-dataframe/blob/27b1cc62255ac971d53f51f65670e6f072c2cc23/index.js#L106

Then I can check '|| row.includeInExport' prop on this line:

react-pivot/index.jsx

Line 276 in 7ff565e

if (excludeSummary && (row._level < maxLevel)) return

But this requires 2 custom forks and feels messy.

(Apologies if I should just be doing a pull request or similar, I'm not quite sure of the right approach, and there's likely more elegant ways to make the same fix, so I thought I'd raise an issue instead).
