EBSCOhost: Asyncify

Looks like we're calling processDocuments in a loop, resulting in a 429

[zoe-translates]

There's a cascade of rapid-burst network requests:

doWeb for multiple -> processDocuments in loop -> callback calls doGet -> callback calls processDocuments under some conditions

I'm tempted to write some fixes, but I need to test on something, and I'm afraid that requires a subscription.

If you want to try anyway, I can test it and make final tweaks.

Thanks, that would be nice. But without some live data, I can't explore the opportunity to eliminate some requests. I can only do a mechanic transformation into the async style (and maybe replace the encoding routines -- involving a custom implementation of btoa() -- with the more modern TextEncoder).

[dstillman]

That's fine to start. It's the burst that's the worst.

Nice anapestic dimeter. You really know how to motivate me.
