[Bug report] year option fails

[nikohansen]

With the cocoex installed from the current master branch

import cocoex
for sname in cocoex.known_suite_names:
    print(sname, flush=True)
    try:
        suite = cocoex.Suite(sname, "year: 2022", "")
    except e:
        print("{} raised exception {}".format(sname, e))

crashes the Python kernel already for the first bbob suite. Namely, it also fails on the bbob-largescale suite and works on the others.

Expected: the above code runs smoothly.

I pushed a small change in the code to development which addresses the above and passes the test for all years from 2009 onwards.
