How to use export data using `ui-grid-exporter` with pagination.

[sohampshetty]

Currently, ui-grid-exporter works internally to export data. But I'm in a scenario where I want to export thousands of row which are not currently shown on the ui-grid-datatable because of the pagination.

Right now we can:

1. I can do selected export
2. Visible row export
3. All data present in the grid.

What I need is, I want to customise and want to pass an array of object to the exporter to export.
