Availablility of Pretrained Models

[JacksonBurns]

Hello - from what I can tell in the docs here and this code:

graphium/graphium/utils/spaces.py

Lines 151 to 152 in d12df7e

	GRAPHIUM_PRETRAINED_MODELS_DICT = {
	"dummy-pretrained-model": "tests/dummy-pretrained-model.ckpt", # dummy model used for testing purposes

There are no pretrained models available. I'm specifically interested in those from Towards Foundational Models for Molecular Learning on Large-Scale Multi-Task Datasets, though it seems like you may have added some others models that use at least a similar approach, if not the same training data/scale, in #52.
