gradle test fails due to wrong DATASET_URL #45

TestData.java
private static final String DATASET_URL = "https://panako.be/releases/Panako-test-dataset/"

it should be:
private static final String DATASET_URL = "https://0110.be/releases/Panako/Panako-test-dataset/"

However, the main problem is having a dependency on a remote web server which makes a test not repeatable (The R in F.I.R.S.T) under certain conditions.
As Robert Martin writes in Clean Code:

Tests should be repeatable in any environment [...] and on your laptop while riding home on the train without network

Caching partially solves this problem, I would add the required files in the repo since the build fails without working tests.
