Provide better system output to indicate tool is still running

[barbeau]

Is your feature request related to a problem? Please describe.
Currently, when processing output for all users you'll see on the command-line something like:

...
Processing user record 1 of 17771

And it will just stay there for a long time (> 10 minutes). But if you check the output folder you can see it's still outputting data.

Describe the solution you'd like
It would be nice to have some indication that the tool was still running on the command line. Either decrease the modulo value for output per user (maybe every 100 users?), or just add a . on every X users to indicate that it's still working.

I think part of the problem is the current wording - it would probably be better if we said:

Processed user record 1 of 17771

...so it doesn't seem to imply that we'll see output for everything it's processing.

Looks like the current modulo is every 1000 users:

onebusaway-firebase-export/src/main/java/edu/usf/cutr/tba/options/ProgramOptions.java

Lines 53 to 54 in 428ba67

	// When to show the number of processed user records (interval)
	public static final int SHOW_PROGRESS_INTERVAL = 1000;

@welozano Let's talk about this tomorrow.
