Support time_increment in config file

[awbauer]

Hi, I submitted a feature request for this with Shaun (via email), but wanted to follow up here. We'd really love to see FB's time_increment parameter supported in this tap.

The reason we're looking for this parameter is to support our use of unique-based data. For non-unique measurements (clicks, impressions, spend, etc), the metrics roll up cleanly into a weekly/monthly/yearly view. However for unique-based measures (reach, unique impressions, frequency, etc), the only usable dimension is the interval pulled by time_increment. For us, this renders the unique-based measures essentially useless; we're never looking at them in a daily view.

Here's a gist that sums up the issue. Take a look at the reach of 258,031 from the time_increment_monthly.txt file, for example. There simply isn't any way to replicate that result from the time_increment_1.txt results. This is a huge issue for us because any reporting we'd be running from this data would be "What was our reach over X period?"

Allowing us to set time_increment to the monthly level would be a massive win for us. Currently, our only alternative is manually pulling the data from the Facebook dashboard.

Thanks for all the work on this integration! We're really thrilled with the potential here.
