The README suggests using firebase-streaming-import for files larger than 250MB. My database that I'd like to import is well over that threshold (6GB+), and with the speed of ~30seconds/MB, that ends up being somewhere around 50+ hours (and has to be run twice). Also, firebase-streaming-import hasn't been updated in almost 3 years.

I'm sure this could be improved, and should be included as a part of this package using node streams (I'd be surprised if I was the only 250MB+ user...).
