Conda support
Nice thanks :) 
Note that in `datasets` the tags are simply the version without the `v`. For example `1.2.1`. Do you push tags only for versions? Yes I've always used tags only for versions
Will push a new version on anaconda cloud every time a tag starting with `v` is pushed (like `v1.2.2`).

Will appear here: https://anaconda.org/huggingface/datasets

Depends on `conda-forge` for now, so the following is required for installation:

```
conda install -c huggingface -c conda-forge datasets
```
