Galaxy metadata for pairing with `smith42/galaxies' dataset

Here we have metadata for ~8.5 million galaxies. This metadata can be paired with galaxy jpg cutouts from the DESI legacy survey DR8, the cut outs are found here: https://huggingface.co/datasets/Smith42/galaxies.

I've split away 1% of the metadata into a test set, and 1% into a validation set. The remaining 98% of the metadata comprise the training set.
