Metalhead.jl test data

The test data of Metalhead.jl, the Flux ports of Hugging Face Hub models: tiny PyTorch fixtures (random weights and the activations of each module) and the outputs of real checkpoints, which the tests compare the Julia ports with. They are written by the scripts of porting/ in that repository.

Each entry is a tarball named by its sha256, under the path of the entry in test/ (fixtures/resnet_basic/<sha256>.tar.gz). test/Artifacts.toml binds each one as a lazy Julia artifact, and the tests download it on first use. Files are only ever added, so every commit of Metalhead.jl keeps its test data.
