test data release

[gshuangchun]

Thank you for your contribution!

I cannot reproduce the results in Table 5.1. Could you please release the test npz files? such as
test_data = [
"cvrp/test/50.npz",
"ovrp/test/50.npz",
"ovrpb/test/50.npz",
"ovrpbl/test/50.npz",
"ovrpbltw/test/50.npz",
"ovrpbtw/test/50.npz",
"ovrpl/test/50.npz",
"ovrpltw/test/50.npz",
"ovrptw/test/50.npz",
"vrpb/test/50.npz",
"vrpl/test/50.npz",
"vrpbltw/test/50.npz",
"vrpbtw/test/50.npz",
"vrpbl/test/50.npz",
"vrpltw/test/50.npz",
"vrptw/test/50.npz",
]

Hi @gshuangchun ! Thanks for reporting the missing dataset - we forgot to upload it. We updated it alongside several bugfixes, enhancement, and automatic testing :)

Feel free to report any further issues~
