Provide API access Dey_Deeplearning dataset

[bschilder]

Break up and store files from Dey_DeepLearning.tgz in a GitHub repo so users don't have to download entire dataset (37GB).

Extend DEEPLEARNING. to connect to these remote resources by default.

Ideally, will tabix-index all files as well to improve querying speed.

Also of potential interest:

Dey_DeepBoost_Imperio annotations.

Would like to do the same for SpliceAI results, tho need to check the license agreement first.
