Feature proposal - indeterminable progress bar (unknown total)

[lbeschastny]

In some situations you may not know the total number of ticks, but want some progress reporting nonetheless.

Right now I have two particular use-cases in mind, but I'm sure there are more:

1. HTTP downloading with unset content-length header.
2. Parsing data feed of some unknown length.

Here is how I solved this problem in my clj-progress module (node-progress port to Clojure):

(with-progress-bar " [:wheel][:bar] :done/:total :elapseds :percent :etas"
  (init -1) ; non-positive total
  (...); some code calling (tick)
  (done))

It will be very nice to have something like that in node-progress as well.

If you'll approve my proposal, then I could try to implement it myself based on my previous Clojure implementation, and send you a PR. Though I'm not sure when I'll manage to find some time to do it.

Attached my PR with proposed implementation and usage example.

Code is out of date. Needs to be updated before considered @lbeschastny

This is a very helpful feature and wondering if this could actually be made available officially via this package.
