add 2 more styles of test data per #199

[ndushay]

The main idea is to ensure we have test_data that mimics the data we actually expect.

The next idea is for our test data folders to be named so we know what's in them.

My intent is that we eventually get rid of the bundle_input_xxx directories. Happy to add such commits here, if folks want. Happy to make a follow-on ticket.

Mostly, wanted to ensure we could run the code with the test data mentioned in #199. I ran the discovery report in the console for these new dirs (and for images_jp2_tif)

connects to #199
connects to #218
