Test files are too big (they take about 20 MB)

[markotoplak]

It is nice if packages include tests and test files, if possible. This package is not nice because test data is ~20MB and thus should not be distributed (it currently is, though, and it makes this package needlessly big - it is about 10MB).

It would be great if we had smaller test files (total size <1MB). This is usually easy to achieve by just taking a portion of the file in question or making a smaller measurement.

For reference, see how much I bugged Quasars/orange-spectroscopy#739

Now we screwed it up already a bit because these big files will always be in the repo history, but this is not such a problem because it does not hurt end users, just developers. Please be mindful of what you commit in the future.
