r.stats.quantile: minimalistic testsuite added

[neteler]

This minimalistic testsuite triggers #2259 (segfault in r.stats.quantile).

The bugfix of r.stats.quantile in #2323 should make let this test pass.

Verification of the results would be nice (the TODO in the test):

I have no clue how that would be done...

See e.g. https://github.com/OSGeo/grass/blob/main/raster/r.info/testsuite/test_r_info.py for inspiration. Essentially, you simply need to provide a reference result against which to compare the test results.

It seems that it is only working for r.info. I adapted it (810bbd7) but get

Or am I missing something?

Thanks @petrasovaa for updating this test!
