Downloading datasets throws `KeyError`

[laserkelvin]

I'm trying to test out downloading some Colab Fit datasets, and wasn't sure if things weren't completely settled just yet.

Running the following command fails with a KeyError:

colabfit query -t ABC2D6-16_PRL_2018 -d xyz

Found 1 Dataset(s) on the ColabFit Exchange!

I get the same error for both -d lmdb and -d xyz.

On an unrelated note, there aren't installation instructions on the README. I just ran pip install git+https://github.com/colabfit/colabfit-cli and could be something you add to the docs?

The exported dataset themselves are still in flux as we go about standardizing them. I will disable the download option in the meantime and add installation instructions. Thanks so much for pointing these issues out.
